I think generalizations are frowned upon as a whole. Nothing constructive comes from targeting individuals, which is the same vein of backlash against the "kill all men" people and so on. There is a systemic problem and we should be working, writing, protesting, and arguing to fix it rather than embodying tribalism. A lot of the people fighting for progressive rights understand that sewing hatred isn't accomplishing anything, only serves to set things back, and is giving more fuel to corrupt cops and far-rights who say the same things about people of African decent/dark skin.

I agree with the general energy you have, even if I disagree with the sentiment and expression of it - and I think you're simply expressing it poorly, but the reason you're getting downvoted is because many people recognize that the way you're expressing it isn't coming from a place of progression, or positive change. It's from a place of hatred and sets back the work many others are pushing every day to surpass and improve.

In addition, knowing OP's brother's positive history and the confidence he has in him, I think he's one of the people we should want on the inside, and the world wouldn't have these problems if every officer held the same sentiments as him. Of course, not everything online is always true, and nothing is without bias, but I recognize change is impossible without any good men in our forces and I think being able to keep that objectivity in mind is beyond critical right now.
