Do you really need to call them white trash?
Well, I don't do PC very well.
I still sometimes use the "N Word" to describe black criminals who behave in a similar manner, so I guess "white trash" isn't overly harsh or inappropriate.
"White trash" is what they call people like these in my little home town in the mountains of Pennsylvania, and have for for the past hundred years or so. It doesn't mean the same thing as redneck, a term they actually embrace, it means a totally reprehensible white person, like these bums.
What would you suggest?
