I'm sorry. Racism should not be ignored. But I'm not sure how censorship initiated by the provider solves it. It is truly a tragedy that you had to shut your site down, and I think those that caused you to have to do that should be punished. However, when a provider starts censoring specific types of speech, there is much left ahead that they will be asked to censor, which is all I was trying to say.
I hope that you and your brother find a safe place to share your information without being harassed.
