Any time people say jokes shouldn't be allowed, I get the heebiejeebies.
That applies to the dude who came into my village and made a joke to me (probably because we're both white) about dental hygiene. It was in poor taste, and I didn't laugh... But he should be allowed to make it. And it should apply to the stupid white tears mug. Maybe it's in poor taste, but it's a joke, not the guy coming in and burning down your house because you're a white person. Humor is one of the better ways for people to deal with things. Especially uncomfortable things, like racism. Censoring comedy is bad, even if it's not funny for you. Of course, taste should be considered, and if someone's making crass, awful jokes, you might be like "This is a crass, awful person", and maybe even make a comment to the effect of "dude, no".
And yes, he's a public figure, blah blah blah. But he's a game developer, for crying out loud! He's not someone who has to carefully try to represent and please the most people, like the president.... Oh goddamnit.
