hope this clears it up.

Nope, doesn't clear anything up. Redeclaring your statement doesn't really answer any questions that arose from your original statement.

I still have these questions: What is a marginalized group, and why is that important? Why does being an "authority figure" mean it's okay to overgeneralize?

You're declaring these to be important factors in whether or not it's "okay" to overgeneralize specifically for the purposes of demonizing an entire population. I'm arguing that generalizing like this is never acceptable. In fact, I'm arguing that doing this is actively harmful to the goal you ostensibly are serving by demonizing this group in particular (unless you have ulterior motives, I suppose).

You have yet to explain why it's acceptable, and what makes it acceptable. Further, you should explain why overgeneralizing like this is useful, and how it actually furthers your goal.

Actually, I'm not sure what your goal is, other than to spread hate?
