Fuck him

It almost sounds like what you really bothered by is that you haven't said anything to him about his racist comments. Perhaps you have, but that is not mentioned in your narrative.

if you're a "I forgive all person" then why did you write the post? It obviously bothers you. It bothered you enough to look up the word "shirt" They get to be a racist but you can't swear? You do hate the guy--nothing says you have to admit it to anyone. Do you trust them? Would you have a beer or dinner with them?

Explain to him his personal opinions on other races and people are not to be expressed at work. Other than that leave the guy be he has enough problems as is. Some people are ignorant by nature and it nearly takes a miracle to get them to see anything other than disdain for things that are different.

Talk to HR about him.

Seems like a company problem if they do nothing about said person. You could report your company to the labor agency that handles racial discrimination, secretly. In today's environment that would get you traced and fired, illegally, most likely.
