(Yes Salmon I already know you are different from everyone else when it comes to social situations, your personal testimony is clearly a thing that refutes my own experiences.)
I'll admit to reacting something like this when it comes to some things, like game design or favorite movies or music or the like. It's easier for me to understand how personal values are connected to those things, and how disagreement can feel like an affront to those values or simply a divide with someone you want to connect with.
Food and drink, on the other hand, are physical sensations you either like or you don't.
Alcohol... I get the whole 'social lubrication' theory... I can understand why people would see something in the act of getting chemically stupified together... sort of... but damn can people get insensitive about it.
It's not like "You don't like ___ band? Really??? Have you tried ___ song??" which might be annoying to a person at worst but is otherwise totally harmless banter. Plus, people typically react with mere disappointment if they fail to convert someone to liking something.
Compare with "You've never drugged yourself into a stupor? Seriously? Hey everybody! This person has never fucked themselves up! *gasps of disbelief from everyone*" leads directly into social pressure to get a person to directly betray their own values. If they fail, they tend to get genuinely offended, rather than just disappointed.
So I kind of get it, but it still bugs me. It's a social pet peeve of mine.
The silver lining is that the more that people are aware of your nature the cooler they generally are with it. Just be a cool friend who is enjoyable to be around and they gradually stop caring.
At least this is generally true.
