No flame coming. But I do disagree. I think most people don't fear actually catching a disease. It's more a disgust of coming into physical contact with the various secretions of people with whom you do not have a close relationship with.

You're kind of putting your head in the sand, and you can get away with it because you don't know what happened in that hotel room before you arrived. If you could see the previous guest not wipe well after a BM, and then use the remote and sit naked on the desk chair, would you still be so cavalier in your attitude?
