Those are hardly negative, and to equate their tone with far right rhetoric is textbook false equivalency. They are if anything just positions that one may or may not agree with about the just distribution of wealth and opportunity.

None of them are even in same ballpark or kind as the current toxic rhetoric on the far right, such as "[Mexicans] are criminals", "Muslims are trying to impose Sharia law in the US", "blood and soil", "we can't rebuild our civilization with someone else's babies" (that one is paraphrasing from a sitting member of Congress).

That is the rhetoric of racial and ethnic nationalism, which is almost totally a far right phenomenon on social media. There is no equivalent on the far left today, and that's not to say that it can't develop. But to do so with literally require a complete change of the people who make up the left.

Social media and regular media both contribute to this perception because everyone wants to forget about their own bad associations and focus on the bad associations of others. So, if you want to find out about nationalists you read left-leaning publications and if you want to find out about radical-to-the-point-of-silliness leftists you have to read right-leaning publications.

3 of the 4 examples of right wing rhetoric I quoted were uttered publicly by right wing elected officials (including the highest current elected in the land), not by people entertaining themselves on Reddit. The fourth was shouted publicly by crowds in Charlottesville.

The difference between right and left rhetoric is one of kind, not degree. Ethnic nationalism is not a motivating factor on the left today.

Class tensions and frustration over the distribution of opportunity and wealth - yes, those are prominent left-wing issues and that rhetoric is often expressed via insensitive metaphors targeted at the very wealthy, but again, it's not even comparable to the rhetoric of ethnic nationalism.

I said that the far left doesn't use ethnic nationalist rhetoric. That acknowledges their existence.

I think we'll eventually see a second generation of social media platforms that incorporate the lessons learned from this generation.
