Ask HN: A VC was racist. I called him out and he blocked me. Is this OK?

I wonder if this will ever end. I enjoy following Andrew Wilkinson (of MetaLab) on Twitter, and I admire his work and tech advice. The incident happened after he insulted Saudis, specifically calling us people cutters, after a tweet from Trump. I sent him a private DM, respectfully telling him that these hateful statements are not fair at all. He deleted the tweet, and simply blocked me. This incident is bothering me since that day. Is he supposed to insult people, and we should just let him be?
