It's not hate on the secondary vessel, it has it's purpose (though a lot of things folks use it for like dry hopping CAN be done in an extended primary.) It's just that a lot of the reason folks use it comes from the old yeast fear about autolysis. So much so that many brewers are so scared or go by airlock bubbling instead of hydromter readings that they will rush their beer out of primary and into a secondary.
BEFORE the beer is even done.
A lot of them are influenced by the first edition/online edition of How To Brew- Which Palmer has admitted he wasn't quite on top of things with and caused a bit of a newb panic.
THEN what's usually the case is that we get a thread like "Is my beer infected?" where they post a picture of a glorified krausen (which since they've used a bucket they may never have seen it) because moving the beer mid fermentation they krausen re-starts.
Which is less of a big deal than the OTHER threads they start which includes their beer actually getting stuck because they took it off the best amount of yeast to finish the job, or yeast bite, because the yeast hasn't flocculated out, or off flavors because the yeast hasn't had a chance to do their job.
Not to mention what Palmer and Jamil have said int he last year about not moving to secondary because of the risk of Oxydation or Infection.
Or just the fact that kit instructions suck and leaving the beer even a few days longer in primary after fermentation is complete
to let the yeast clean up those byproducts of fermentation which they created. I mean even John Palmer mentioned that in the same edition that he talked about autolysis
. He advocated leaving beers a little longer on the yeast.

And, three weeks in the primary fermentor is usually not enough time for off-flavors to occur.
One of the big ones that the yeast will clean up if given time is Diacetyl- Professor beer explains it well.
Three pathways lead to the creation of diacetyl. The first is through normal yeast metabolism. Brewer’s yeast form a precursor called alpha acetolactate (AAL), which is tasteless. This compound is converted to diacetyl as the beer ages. The reaction that changes AAL to diacetyl is accelerated by high temperature. At cool temperatures it will still occur, but more slowly.
Modern brewing practice dictates that beer be aged on live yeast until the vast majority of AAL is converted into diacetyl. Brewer’s yeast, while unable to metabolize AAL, will readily absorb and break down diacetyl into relatively flavorless compounds. By giving the beer enough contact time with the active yeast, the brewer can eliminate the diacetyl. It generally takes only about two weeks of aging an ale to assure that it will have no buttery flavors.
And following the 1-2-3 rule is, or arbitrarily moving the beer after a week, beause of instructions, is plain silly with the normal 72 hours lagtime you often get (as mentioned it the sticky in the beginner's section)they may only actually be fermenting for 3 or 4 days before someone arbitrarily moves the beer...As mentioned earlier, that leads to stuck fermentations, krausens in secondaries and those dreaded off flavors (because the yeast hasn't had a chance to clean up after their own byproducts of fermentation, if you move them before they get to that point in their life cycle- which is the true secondary phase, the cleanup phase.)
The problem is, contrary to what you might think, yeast can't read recipes, or follow calendars, so they don't know when they are supposed to be done, and have their own timeframe.
If folks DO choose to use a secondary, I recommend folks don't even take their first one til day 12 and the next one on day 14 and then rack to secondary if you are choosing to go the secondary route. That way you do get some of the clean up time that you get from having contact with the greatest amount of yeast, which will get rid of the byproducts of fermentation (such as diacetyl) and make sure fermentation is actually complete so you don't get a stuck fermentation.
I find some combination of a month, whether it's a month in primary or 2 weeks (if fermentation is complete) in primary and 2 weeks in secondary seems to bring out the best in most beers.
I find int funny that people say that "X beers need to be consumed young." You still only want to consume them young if they're actually finished, it doesn't mean a beer is meant to be drunk GREEN.
A beer still will need to clean up after itself, it still might need to bottle condition, and for sure it needs to be CARBONATED before you want to drink it (You can't really control how long a beer in a bottle will take to carb up.) A young beer doesn't mean a crappy unfinished beer......you don't just decide that my beer is going to be ready from grain to glass in 10 days (especially you bottle.) It just means that you don't need to sit it in a secondary or bottled in a dark cellar for 6 months.
I don't think there's hate for secondaries (I still use them for big beers, or fruiting or oaking).....it's just not the be all and end all any more, ESPECIALLY if it's being done because of yeast fear like it was 30 years ago. They did a lot of that because the yeast WAS crappy.
The yeast 30 years ago used to often come across on ships in hot cargo ships, and OFTEN the only yeast folks COULD use to make beer was this;
(Which probably wasn't all that "fresh" to begin with. And probably wasn't even stored cold, like we do even with those little foil packets.
So yeah, rushing the beer off the yeast might have been the best course of action, but even Palmer admits that isn't the case anymore. That contact with modern, healthy yeast for a little longer may be beneficial for our beer. Most of us who long primary have experienced that to be the case.
But it's not that there's "secondary hate."
