Wow. It IS racist. "Hispanic, white trash, and black" Did you notice that you qualified WHITE with trash? It sounds like, from the description, that all of "these people" are trashy. But to you, it's only "trashy" when White people do it and it's normal (hence the lack of a qualifier) when other racial groups do it.
Themself is not a proper term.
When have you actually talked to "these people" to see what respect they have for you, for their other neighbors, for their family, for anyone else - since you "know" they have no respect for anyone else? It certainly seems with all of the judging you've got going on, that there's a lack of respect in the neighborhood. I'm remembering something about "taking the plank out of your own eye before the speck in your neighbor's." Someone famous said it - look it up.
Finally, "The police are taking daily calls to the same homes and same apartments." Well, it sounds like specific PEOPLE are the problem and not "Hispanics, white trash and blacks." Might we not look into individual action instead of lumping communities together?
