Sounds nice if you rattle that off quickly but actually, why?! Nobody I know has been informed of what I think is morally wrong about their lifestyle. I think a lot of people would consider, if the premise of an exchange is a moral judgment against for you going about your normal life, we are into territory someone should keep to themselves until absolutely practically necessary, certainly in blighty. Just like religious requirements etc.
Oh, come on, virtually every thread on AIBU (and large sections of the rest of Mn) rests on people forming negative judgements of other people's parenting, manners, hosting, drinking behaviour at the school gate, inability to stop folding their DIL's knickers/watering down their Fairy Liquid on visits etc etc. Anything you do, however innocuous (washing up bowls? saying 'pardon'? how often you wash your bra?) is up for potential judgement.
For clarity, I can safely say that never in my entire life have I said 'I think that your meat-eating is morally/ethically-wrong' to meat-eating friends, including people who hunt their food, and those who aren't fussy about battery chickens/cheap meat etc. I have never initiated a conversation about vegetarianism. But, as attested by many posts on this thread, apparently I don't have to say anything. The mere sight of me minding my own business and eating something vegetarian across the table is an implicit reproach, which makes complete strangers start to shriek about carrots screaming when you pull them.
