I don’t think this is true at all. Hazy IPAs have a very different flavor (lower bitterness but more steeped hop character) and mouthfeel to me. It sounds like you’re saying they’re just WCIPAs that look funny.
I'm not trying to change anyone's opinion or tell anyone they are wrong. I'm only pointing out the technical aspects of each beer as outlined by the BJCP.
I've been lucky enough to taste well over 100 neipas thanks to living in New England. Slapping a neipa tag on a beer almost guarantees it will sell. At least the first go around. People pick up on the really good stuff. I've had them range from clear, to slightly hazy, to what looks like liquid yeast and every where in between. I've also had them taste like juice, and I've had them taste so bitter it seems like I'm biting into a hop pellet. There's so much variation, and people just taste beer differently. Among my group of friends, I'm the one that prefers less bitter. And there have been times when I think a beer isn't that bitter, and my friends will tell me it's a bitter bomb! So much for perception...
Onto a regular pale ale or ipa or apa. West Coast vs East Coast is dramatically different. West Coast is more bitter up front. Piney, yet citrus, even fruity. Usually clear. Here on the East Coast, pales tend to have much softer bitterness. It's still up front, but the malts tend to come through a bit more and even things out. I was never a WC fan, but I can appreciate the style, especially on a scorching hot day.
As for haze. This is what polarizes people. Old school = no haze. Haze = lazy beer. I've heard it over and over again. That's just opinion. Opinion's can be held on to for too long for whatever reason. Evolution in beer is what made the neipa possible. The last 5 years have been amazing for the New England beer scene. CT, where I'm from, has seen the number of breweries jump from 25 to over 100, with another 20 slated to open in 2019. They ALL have a neipa on tap. It took some of them awhile to jump on the wagon, and each brewery does it differently, but they all have one (or more) on tap. Not saying they are all good (me being a beer snob doesn't help their case) That being said, most other styles tend to have haze! Not sure if it's chill haze, or no filtering, or rushing beer, but I've had pilsners and blonde ales that have haze. Not juicy fruit haze, but they sure aren't clear. And the general consumer has no clue. For us, we know better, but we still drink it. Would you honestly order a blonde ale and push it away it tasted ok but had haze. I would guess no. Neipas are hazy as a byproduct of production. Lots of flaked adjuncts, lots of dry hopping and the use of low flocculating yeasts. I've seen people argue about the use of flaked adjuncts (both for and against), but as home brewers, they are an easy way to increase mouthfeel, and what some people believe to be added hop flavor.
Neipas are absolutely ipas. Having haze as a byproduct of the recipe shouldn't be frowned upon, IMO. I guess if you don't like it, you don't have to. But to flat out say because it's hazy it isn't a neipa isn't true. You technically could let it sit in the keg for 6 months and have it clear out. But then you'd lose the intended hop flavor. At what cost? To have it fit firmly into the ipa category? No thanks.
