Your parent comment gave a paraphrased example of discrimination against a group, not a person.

> you should not interpret it as aggressivity

Your parent comment didn’t describe it as aggressive, they described it as dehumanising. There is a colossal difference between the two. Patton Oswalt demonstrates:

Note: I don’t have a Twitter account nor have I ever encountered Dimitry’s writing, so I’m not commenting either way, but if you want to refute/contradict/disagree what your parent comment said, it’s important to respond to the point they made, not different ones.
