No, I don't think any of that should be banned--but at least two of those members you quoted are trolls.
Yeah, two of them are obviously just troll accounts. Big Dicks is almost certainly just somebody's alt account he uses to troll and post inflammatory crap.
Trolling IS against the rules, but that's a huge gray area as to what constitutes trolling. My suggestion is that if you don't like what someone writes, put them on ignore. Problem solved.
The issue is when people just start doing it to inflame and troll which there are a few that obviously are. As you said, people should just ignore those that obviously annoy them so much, but there are also people who overstep the line and just say things to be disruptive.
I don't know why are race issues/religious issues even mentioned on technical forum
Because we have a Politics & Society sub forum, though you could certainly argue we don't really need it, but it's there and I doubt it will be removed and I don't think it should just because sometimes people say things that annoy or hurt others.
The Qu'ran has very negative views on homosexuality.
So does the bible.
Islam is like living in the stone ages.
So is Christianity.
There have also been many honour killings/rapings/acid attacks in the UK committed against Muslim women in the UK by their own community.
Only muslims kill are rape and do acid attacks in the UK? Most of the rapes that happen are probably done by drunken white males on the weekend. Half of them probably even claim to be "Christian" too. Would that be that relevant?
Also Google ‘Muslim grooming gangs UK’ and see what you think about what you’ll find. Fucking animals!
Why is their religion relevant to this? They don't rape because of their religion and there are plenty of paedophile rings run by whites and every other race, but this rhetoric is just used to incite race or religious hatred. Jimmy Saville is probably the biggest paedophile the country has ever seen, but nobody is calling him a Christian paedophile. If you're against rape then be against rape, but if you only get irate about a fraction of rapes committed by certain people then your biases are obvious.
