Obnoxious behavior is not endemic to blacks and expectations related to civil behavior are not owned by whites; so why is this a racial issue?
Behavior is the key; not color. All people can be civil and it’s more than reasonable to expect it when living in close proximity.
If you were cursing and loud (even if unintentionally), you were in the wrong. We’re all in the wrong sometimes — just move on already. It’s really not about you. Much less your race.
