I'm not suggesting that they can't like cheap beer, just that the vast majority of them are going to pick a different cheap beer, in part because of exactly the situation talked about in this article as well as other similar things in the past. I'm also aware of other examples, E.G. there are LGBTQ+ gun clubs, but they exist at least in part because of the over-representation of the MAGA crowd among gun owners. I've been to plenty of gun shows, and it's incredibly uncomfortable as a non-conservative to walk around and see all the confederate, MAGA, and just straight up racist paraphernalia being displayed prominently (to say nothing of the overheard conversations which are even worse). Does that mean that non-conservatives or non-straight people can't be gun owners? No, not at all, although they are statistically in the minority, and it doesn't help any that many of the retail locations for guns as well as gun ranges are at least somewhat unwelcoming to non-conservatives for a variety of reasons.
There are cultures around certain things, particularly brands, and those cultures do at least to a certain extent impact the popularity of that thing with certain demographics. This isn't some hard and fast rule, like no, as a Democrat you're not allowed to like or own a big ass Ford Truck, but if you picked the owner of one at random, there's better than even odds that they're a conservative. If said truck also has truck nuts and/or is blowing clouds of black smoke out of its tailpipe those odds shift to a near certainty. Is it impossible that there could be a liberal gay owner of a Ford F-150 with truck nuts and a confederate flag pinned up in the back of it? No, not impossible, but it's certainly incredibly unlikely.
