What's crazier? Protesting against the result of a democratic election in another country or chanting "This is what democracy looks like" while protesting against the result of a democratic election in another country?
Plus, in America, leftists are actually now protesting against the Alt Right movement itself, not just Trump. Demonstrating in favour of your opinion is one thing, but demonstrating against the fact that someone else has a different opinion manifests a fundamentally totalitarian impulse.
Also note that in both of these protests, almost all of the protesters are of European ancestry. The brown people are subjugated for now and basically accept that Whitey has won this one.
