No need to apologize for other people's bad behavior. Craft beer doesn't have more snobs than any other group of passionate people-- certainly not more than fancy food-- but the nerdy one-upsmanship is much more prevalent. I think for some of these guys it's their equivalent to trash talking about sports or other kinds of fandom, and for others, it's a way to quell insecurity about their own knowledge level in a realm that they consider competitive.

I worked in bars and restaurants as a side gig for about 15 years and full-time for a few so the sheer number of people I've encountered naturally means I'll have encountered more dinks than most. And because of my food/bev-industry-heavy social set, I've spent quite a lot of time in the more "serious" craft beer bars, and those are magnets for that type. That said, I've also spent a ton of time in high-end restaurants and wine bars and never had anyone make snide comments about, say, ordering a more straightforward wine or a cheeseburger (but in kitchens, I've definitely heard chefs talk shit about people ordering burgers... mostly because they're frustrated more people aren't trying their more creative offerings. And then they go home and eat hot pockets for dinner.) And most sommeliers I've encountered are so worried about coming across like snobs that they almost overcompensate.
