While the article is true in that the liberal press did spend a lot more time on Gibson, one has to remember that Gibson is a much bigger star than Richards. Richards is a has-been who is not even known to most people by his real name.
I am a huge Seinfeld fan but guess what I would not have know who Micheal Richards is. I know the other main characters' real names. Strange. But anyway for whatever mental reason I have always liked Mel Gibson and I quickly forgave him for his insults. Yet Micheal Richards, I just don't care. I'm willing to let him twist in the wind. I'm horrible.
