Haha human rights, free speech? Give me a break. There's no free speech in the world. Just go outside and start shouting racial slurs. If you're a white guy and start walking around the streets in the US, the land of the free, saying that all niggers should be hanged and KKK rules you'll either be arrested, beaten, or killed, depending on the area where you decide to do it.
You may have your own opinions but the forum is being maintained by by admins and it's their choice if they allow you to express them or not. I've seen many people banned because they were talking shit and trolling.
