Not exactly sure what you’re asking, but no, collective nouns aren’t generally pluralized in English, nor is the term appropriate outside of a porn context. Are you a native English speaker?
Blacks and whites. Indians and Asians. Look, it’s plural. Add an S, guess it’s dehumanizing? I think the term daddy is dehumanizing. Please, only use dad. Do not add another dy.
Yes, generally referring to groups of people as pluralized adjectives is considered dehumanizing.
Note that Blacks and the Blacks are both considered offensive and should not be used. Black people is the preferred plural form of Black.

[A]im to use Black as an adjective, not a noun. Also, when describing a group, use Black people instead of just “Blacks.”

This is for the exact same reason you would not refer to a singular Black person as “a black”. If you still have trouble perceiving the issue, consider how jarring the term “a gay” would seem in print.
I didn’t say “a black”, context matters no? Everyone thought saying Indian was offensive and came up with native American, until realizing that is more offensive? Just because it’s plural doesn’t make it dehumanizing. Black people says blacks, I don’t hear them say a group of black people.
It’s far more acceptable than “blacks”. It also avoids the issue of associating general search terms for groups of people with sexualized contexts as has unfortunately been done to Asian women and others.
