Why is there a lot of sexism against John McCain?

At my work I always hear people making fun of McCain's sex life and how he needs viagra and stuff. Why is there sexism against John McCain like that?

1. Because is A*S is old!
2. Because he likes to verbally abuse his wife and is an adulterer.
3. I DON'T THINK THAT IS SEXISM.....YOU MIGHT BE CONFUSED. IF ANYTHING, IT IS AGE-ISM.
4. um... sexism is degrading someone bacause of thier gender, not making fun of someone for thier lack of sex. I'd be more like Ageism, just making fun of him because he's old. Not that that makes it OK, I'm just saying....
5. That's not abut his gender
6. maybe you work as a rep for Viagra?
7. That's just the way it works. If you can't find a valid criticism of his proposals and agenda, drag the conversation down to a more base level for entertainment purposes. I'm not sure viagra or anything else could help the situations in either the Clinton or Obama households.
8. Because McCain votes against women issues. I know I have say a thing or two about it because he voted against women equal pay bill.
9. Ignorance! Lack of intelligence!
10. Wow. The people in your office must be REALLY ignorant. McCain has a penile prosthesis and has no need of Viagra.
11. It's more ageism then sexism. You can't really blame them. He's ancient. Sexism is when the media makes fun of Hillary's cleavage and pant suits.
