There is no guarantee, and if you look like a sufficiently valuable target, you may be attacked regardless, however…

Being attractive and high-status is a major defense against many forms of social attack.  People will like you and make excuses for you, when they won’t for equally-deserving others that are less handsome and less popular.

It can help even in environments that say they are against lookism and unfair benefits from popularity.

The best defense against this particular accusation, of course, is to be born cis female.  (Of course, that’s still only a partial defense.)
