Can I ask for some assistance?

I have written an article that would surely be controversial about racial issues, and I'd like to publish it on the internet. It has to be done anonymously, or I'd have the police on me claiming it's "hate speech".
How do I go about it?

If it's removed, I want to keep reposting it, so I can get some responses to it, and get a feel for how others feel about the views expressed.
What is the best way to post anonymously, so it can't be traced back to it's source?

Thanking you in anticipation.
