Trying to help a person figure out what tastes they don't like is like trying to describe red to a blind person, or jazz to a deaf one...It's hard because things that are sense driven, including our tastes, are really subjective....Personal.
For example, although you and Parker don't like Bud Ale, I don't think it's that bad...I think it's surprisingly malty and flavorful for a macro production...so I will drink it on occasion....and at the same time I see nothing wrong with spending 17 dollars on a 4 pack of something by Dogfish Head....And I love extremely hoppy beers as well...
I think what you need to do is find a store that allows for doing mixed sixers of micro brew, it's a good way to try different styles and it's often a couple bucks or more cheaper than buying an entire sixer of one micro...for example I can get a six pack of bell's two hearted for about 12 bucks...but at the same beer store they have a cooler for 9.99 mix and match....and you never know what they will stick in there...so if I'm not in the mood for something in particular or feel like expanding my horizons and not risking an entire six of something I might not like.
So far I've only had a couple bottles of something that I could say I wouldn't have again.
But I've also discovered a bunch of new breweries that I might not have if their beer was in the 12-15 dollar a six.
And I've also gotten turned on by a few beers in styles I never thought I'd try...Like Vienna Lagers....I've never been a fan of the fizzy yellow type of lagers, but damn those brown, malty Vienna ones are fantastic.
If you have a Trader Joe's in your town they usually allow for mixed sixer filling as well.
Grab as many different styles as you can get (and then if you like a certain style go back and get as many different versions of the samestyle.)
THen look up the info on the beer and the style at
BJCP 2008 Style Guidelines - Index
It will help you get a handle on the different ingredients that go into the beer...plus you can usually google the beer and find out sepcific ingredients like the hops or grains...
You may then be able to figure out what specifically you like or dislike about a certain style or a certain beer (like you might not like cascade hops...but like fuggles,) it wouldn't hurt to take notes on the beers...
Also don't neglect the micro versions of the macro beer styll, the American Pilsner...or Light lager...you would be surprised how different a micro brew version of the same beer like budweiser actualy tastes. I know I did...I skipped over a whole style of beers just because of BMC, but I've been grabbing any american pilsners put out by micros that end up in the cooler...many still taste like piss to me, but there have been a few surprises....Like American versions of Vienna Lagers...I am a new convert.
And because of doing this I also brewed my first lager as well (Biermuncher's Centennial Blonde pitched with Saflager)....And so far, based on the hydro samples....It going to be amazing...and much better, to me, than a Bud...or a genny cream.
Anyway, you are going to have to do some tasting (not a ad thing to do) and some research into what is in the beer you like and dislike. That way you can build up a vocabulary of what pleases you, and then you can buy commercial versions or brew your own.
Hope this helps!
