This kind of stuff (not forcing people to drink alcohol, being respectful of vegetarians and even vegans, not smoking in the doorway, are all what people are complaining about when they moan about how "political correctness " is taking over society. Good as far as I am concerned, it's not politically correct, it's common courtesy. I think vegans are silly, but I have enough courtesy to want them to be able to enjoy a meal because it's basic humanity.
When Farage says he is against political correctness, he really means he just enjoys being a jerk to people that are not exactly like him.
