My attitude is what's the point, you can't expect people to agree on everything . I was not a nice person in my early 20's. I went through school being bullied (I even attempted suicide as a result) someone was beating up a friend of mine, something snapped and three of them ended up in hospital and I was threatened with borstal (I had never been in trouble of any kind before, my teachers all gave me good reports)and I got off, but I would not stand by after that if someone was being bullied, I got a reputation and realised my so called friends didn't like me they were scared of me, so I actually didn't have any friends, from that point onwards I've gone out of my way to avoid confrontation. My point is arguing or violence does not solve anything and if you can't agree shouting (or worse) won't change anything if only people could leave egos behind and just say I don't agree with you and never will so let's talk about something else.
