That is probably true. I remember I felt really bad when my high school teachers were openly flirting with students during class.

But there is another side to the coin. If you are attractive, a lot of the nastier people out there will try to manipulate you and gaslight you just to be closer to you all the time. Some people will be cruel and nasty to you just because they know you will sexually reject them. Some teachers will be mean or passive aggressive towards you because they are attracted to you and they know they can never be with you.

It is actually very dangerous to be attractive but not to have the social skills to handle the way people react to it. Many attractive people grow up with these social skills because they grown up as attractive children and they get used to it, but for some people that suddenly become attractive because they lose weight or another reason it can be very challenging. Similarly for people that are just born introverts and don't have the social skills.
