Offensive or bad?

Like a lot of news junkies, I've seen the now-infamous political cartoon in the New York Post from earlier this week.  The folks at GLAAD have compiled others from the same artist and have a video/slide show prepared.  Either this guy is equal opportunity offensive or just bad at humor.

My guess is he's bitter.  The slide show is quite telling.

But, just in case the artist could use some help in the humor department, here's a political cartoon that's actually funny.
