One thing I am seeing constantly now from leftists is that they make a claim, but have no idea how to construct an argument to support the claim. I don’t think they even have an argument based on reason in their own minds. They are just all running on prejudice and hate, even among their university-educated “elites” now.
They do not care. Proof by assertion (a logical fallacy) is enough for them because it puts the notion into their narrative.
