I don't think I am PC as I laugh at a lot of older jokes or clips from youtube that probably are now offensive (it is an interesting evolution). Plus stuff like Archie Bunker, Fred Sanford or Blazzing Saddles probably wouldn't work in this day (maybe that was part of their point?).
I'm also very stereotypical in my assumptions when I am out in the concrete jungle. I don't disrespect anyone and try to be nice and respectful, but, at the same time I am all about self preservation. So, until I get inside my apartment, I judge people as I see them walking toward me or around me and my behavior is reflective of that (for instance yes, I might cross the street if someone, or a group of people make my spidey sense tingle).
