> so you are not open to discuss with him about the topic?

Am I personally interested in discussing this guy's bad ideas with him? No, I have better things to do than try to get him to examine the prejudices that he's so energetically hiding under a mountain of justification. History suggests that most bigots will literally die before they'll change their opinion. And from what I've seen, those who do change don't do it because of reasoned discussion; they instead have an emotional epiphany of the impact of bigotry.

> I am not going to shut up if I think I am right and it is the best for everybody even if my opinion hurts some people. I shouldn't do it indeed.

How brave! If you look at the US's historical record, you can find a great number of (white) people arguing that the institution of slavery is the best for everybody even if it hurts some people. Try the Conerstone Speech, for example, or the Texas Declaration of Secession.

Of course, you aren't that brave. Like most pro-discrimination people you comment from the shadows.
