It's hard, isn't it? Who can decide what someone else can or cannot be offended by? What's silly and what's ok (to be offended by)? Who decides what's silly and what's ok?
If it doesn't offend ME then it's not offensive seems to be a common feeling, but that's not really on, is it?
Plenty of things don't offend me, but I can see that other people are upset by them and who am I to decide what other people feel?
So I think - anyone has the right to be offended by whatever they please, but if they are offended by someone else's opinion, then unless that opinion comes with malice, or is actually breaking a law (racism, disability discrimination etc etc) then it's just tough luck. You have to accept that some people hold views that are going to offend you. And you can argue your point, but they have as much right to their view as you do to yours.
and you can't delete views you don't like in RL, so I think it does no good to do it here.
Oh, and that deep dark sex secrets thread? I got as far as nevereatbrownsnow's revelation before I clicked away in shock! There you go - doesn't float your boat? Click away. Distinct advantage over RL
