Not to generalize, but I have witnessed myself, many Black people are way too aggressive for no reason and have a problem of following any commandment given to them by any authority, be it police, professor, on road, at work, in gym, anywhere. And like I said I have witness it myself.
Not saying every single one but I've seen many. Not exaggerating but the number I've personally came across, at least 50% fits what I said above. No offense to anyone.
In case if my post hurt anyone, I'm ready to delete it, but it was to show the other side.
