I am not sure anyone would really give a shit IRL to be honest. If they asked or it came up in conversation I would not care telling them that I browse the site or what its about.
I wouldn't mind, and they wouldn't really care one way or the other anyway. I'm fairly confident in saying most of our family and friends are good hearted normies who don't really understand the internet the way we do -- but if you showed them some of our cows and their antics, even they would understand why this place exists. They wouldn't be coming here and watching JULAY to post, but they'd still understand.
I honestly don't care much. My GF sees me on this forum all the time, I doubt she has much of an opinion because she has no interest in what this place is or what we discuss here.
Who cares? My friends already laugh at eccentric individuals online, so showing them this site is not going to change anything. Also my friends don't even know English mostly, so I should be fine
