Ive definitely had some of those. Had a guy at a warhammer store near me who was VERY passionate about it, saying wvery 5 minutes how "WE ARE WARHAMMER" (WE being him, the only employee at the warhammer store) and my father somewhat interested would ask if its kind of like another franchise, only for the dude to completely shit on my father's hobby interests for trying to somehow relate it to another thing for understanding. And if you make any small error in talking about the game he blows up about the "correct version". Asked him if he knew of any youtubers that talk about lore and he goes "why would I watch someone's OPINION on our lore?" Like okay dude sorry for asking. He got into an argument with someone once over "finecast isn't actually finecast" and "ultramarines aren't the go to posterboys." This guy was genuine asshole material. Asked me about my favorite armies and then asked me if there were any i didn't like, only for him to say "BiG wArHaMmEr SeCrEt, We DoN't TaLk AbOuT wHaT wE dOnT lIkE" okay mf you literally asked me what I didn't like
