I don't think it's ok to shame anyone for the way they look, whether or not the aspect of their appearance you notice is under their control. I don't give two shits how tall our former president is, or how much he weighs. What I *DO* feel comfortable judging is how it falls in line with his pattern of deceit and hypocrisy.
Judging others is a crucial survival skill. It's how we determine boundaries. We just have to be careful what aspects we choose to judge.
