I am that person! I disagree with "ought to be private". Says who? That line is different for everyone. I post whatever is on my mind and if people don't like it they don't have to follow me. I tend to steer away from people who feel bound by invisible rules of what is and isn't okay. Get wild, be crazy, show the world who you are. Or don't. No one gets to choose for anyone else what their comfort level is.
