Racism is a classic right wing associated political position (far right: immigrants, minorities, deviants, and the far left cause all our problems; far left: rich people and the far right cause all our problems). Anti-muslim racism in particular is associated strongly with the right (including, one can mention, there are 4 US representatives who are Muslims - all Democrats). On China the divide isn't as stark but is still pretty strong, with the right usually more hawkish and the left more dovish. On Russia, it used to be strongly hawkish on the right, dovish on the left, but these days you have both the far left and far right liking Russia and the centre hating it.
Genocide, I can only assume they're talking about Israel. Parties used to both be pretty pro-Israel, but these days Republicans are nearly evenly split, while Democrats are increasingly strongly against Israel (but there's still a very large minority of Israel-supporting Democrats). While opposition to Israel is now majority in the US, on the specific question of "Has Israel committed genocide", it's still a minority view, but growing, with about 3 in 10 Americans (and 5 in 10 Democrats) saying yes (interesting to note, 3 in 10 Jewish Americans also said "yes"). It's a policy viewpoint that's in the process of segregating in the US by party but which didn't use to be that way, and still has a long way to go to reach a fully partisan split.
In short, their statement describing Fark as left-wing but then saying it's a hotbed of "left, right, middle, hard right" made no sense.
