Talk about some massive strawmen, like I said–if someone’s reason for not wanting alcohol at a party is “I don’t approve of drinking and don’t want you drinking”, I consider that to be way out of bounds for any social gathering. Hosting a get together is not an opportunity for you to act in loco parentis for another adult. I never mentioned any of those other crazy things, and no one would consider those things to be “controlling.” But I also am willing to bet no one on this forum has ever received an invite to a party that said “don’t take a shit on the floor”, or “please don’t show up with your dick exposed”, maybe if we were in the habit of partying with Cro-Magnon people or something, sure. But let’s get serious here.
Like I said, I don’t really get sent rules for social gatherings. Maybe in some people’s worlds that is normal, in mine it is extremely not. So if I saw rules with an invite to an informal social gathering, particularly one so informal as a “potlock outside”, I would most likely question the rule unless it was manifestly obvious what purpose the rule was serving. A “please refrain from bringing any dishes made with tree nuts”, almost without doubt would be related to someone with a serious nut allergy being there. There’s really no other reason someone would even bother to mention such a thing, so it’d be obvious and unnecessary. If the rule is “please do not bring alcohol”, that has multiple explanations, some which I would be fine with and some I would not. If I inquired about it and was told a contingent of guests were from a religious custom that forbade them socializing around alcohol, or that there was a recovering alcoholic present, I would have no issue respecting that. It’s literally never been my experience of encountering that, and I have been at gatherings of mixed-religious background where Mormons or Muslims were present, and I know both traditions have varying interpretations of alcohol and how appropriate it is to be around it. At least in my experience those people in the social gatherings in which I’ve participated, have not weighed in on the presence of alcohol. I assume if they disapproved, they decided it was not a big enough deal for them to raise issue over it, and the host of the gathering didn’t feel it was either. Same for recovering alcoholics. We have a cousin who is not only a lifelong and very destructive alcoholic, he has a bad habit of breaking into drinking when around other people who drink–even after years of sobriety. When it is known he’s going to be at an event there’s almost never alcohol. However we don’t actually post a rule about it, because it’s just understood, in the few circumstances where the gathering includes lots of people not familiar with his issues, I think he just gets by. Note that he has regularly been at restaurant dinners where alcohol is on the table too, so it’s not like he actually lives his life sequestered from alcohol. He has never once requested anyone not drink around him. It’s just known that he’s an alcoholic and despite long stretches of sobriety, he has “fallen off the wagon” enough that those of us who know him well are careful about exposing him to alcohol more often than is necessary. But we’ve never felt the need to codify it into rules that people follow.
But, if we did, and we told people about it, I’d expect them to abide, as I would abide if a host did such at one of their gatherings. Like I said though, it’s just never happened.
Now if someone doesn’t want me to bring alcohol to a gathering because they just disapprove of drinking, I’m sorry but I take issue with that. You can run your property like a silly little despotism if you want, but I find that off putting and a sign of being a bad host. I generally don’t try to enforce arbitrary household rules on my guests, and I don’t think hosts should do so when I’m a guest. Accommodating a serious allergy, religious belief, or substance abuse problem is not “arbitrary”, and thus why I would view those differently. Like I said, it’s not about the alcohol as it is about the weird control behavior–I would react the exact same way if I was told not to wear a t-shirt to a potluck. Sorry, but it’s not your business what I’m wearing at an event like that. A formal event it should go without saying you dress appropriately, but you have no business telling me what to wear at a potluck within the bounds of normal human attire.
