Even at church when we do the "meet and greet" thing before the service, I avoid shaking hands. If I can't avoid shaking hands, I use hand sanitizer as soon as I sit down. Who knows what diseases a person carries, or if s/he has just picked a bugger, or gone to the bathroom and not washed his/her hands?
I have always been a germaphobe, but after my husband picked up a staph infection that settled in his back (Emory MD/infectious disease professor says that this staph resides on people's skin), caused him to need major back surgery and lose a rib for the bone graft on his L1 and L2, and caused him to be on IV antibiotics 6 hours a day for two months, I have become even more of a germaphobe.
So if someone who dislikes George Bush for doing what he did while he just happened to get caught on video, I guess that people are offended by me. My advantage is that no one is videoing me nonstop. Do they think I am not "cool" with white people? Maybe so. The only black people at our church are the assistant minister and his wife, and we chose him to perform our daughter's wedding ceremony in June.;-)
