Is masculinity so bad?

Why is masculinity sometimes looked at in a negative light? Any thoughts?

The idea of football comes to mind almost immediately. I’ve heard so many people speaking negatively toward anyone who enjoys such a sport.

Couldn’t it be that it’s just their thing? Is it so bad to be into football? Is it any different than being into sewing or water polo or collecting soap?

In short: Why you (in general) gotta be hatin?
