My wife has been in the medical field for 40 years. Her opinion is your hands are still cleaner if you piss on them and don't wash then if you actually touch anything in a public rest room.
As for transgender bathrooms I have a 16 year old daughter, I'm not politically correct and if I saw a man enter a restroom with her in it I'd drag him, her or it out and proceed to educate them in the REAL world where we live. Us hillbillys do it different then city folk.

The only way sponsoring an Indy Car team works for a company is if the team wins the 500. The general public doesn't really give a damn about the rest of the season. And even if they did, when Indy Car generally only runs every other weekend, and basically ends their campaign before Summer is over, why would a company want to cut a big check for that advertising?
