Nonsense, this is just your perception. You have no basis for this claim. If this is true what is your solution? It will obviously need to be a solution that doesn't interfere with free speech in a liberal democracy. I'd be really curious to see which knots you tie yourself in figuring out this conundrum
Actually, you need to be tolerant and accepting of others, whether that be their views or their characteristics. Those on the extreme right are equally or even more intolerant of others, you know how fascism works I presume?
What you're actually saying is that black people shouldn't be allowed to organise as black people to raise issues of race discrimination. If that didn't happen. nothing would change. Same with women's issues, gay rights etc.
Ironic that your post comes across as full of right wing talking points but no actual solutions to your perceived problems. What would be your solutions that would be acceptable in a liberal democracy?
