Where Is the PD's Racism Threshold?

I'm working on a longer post on this topic, but something struck me as I was reading through the comments on the various PD articles about the roving bands of "urban youth" terrorizing the white folks who just want some peace and quiet on the loop.

This thread is closed to further comments because there were too many racist comments being made. Here, look:

There are other comments in that thread that the editor has removed because of racism. The editorial foot has been put down. Certain things are not acceptable and won't be allowed to stand on the PD's website.

What the editors let fly, though, makes me terrified of one day actually managing to read one of the things they delete. In the comments section of another article about the "Black Kids On The Loop!!!" controversey, this comment was allowed to remain:

I mean, Jesus. We all know what "thugs" really means, and I'm just not sure there is anything more obviously and explicitly racist than literally advocating shooting a particular group of people in the streets.

What could the racists who got the first thread shut down have possibly said to get their comments removed if that one is apparently acceptable?
