Why is “girls supporting girls” accepted but “men supporting men” (if it existed) wouldn’t be accepted?

”Girls supporting girls” is purely sexism as it is based off of siding with women purely because they are women. Since that would be the same with “men supporting men” it would be called out by every feminist under the sun about how sexist it is. Why is it ok for women to be blatantly sexist and not get called out for it?

Why are you making a problem out of nothing? That is men’s specialty. 
A lot of girls are mean to each other so it is a nice phenomenon and you’re trying to make it a bad thing. What is your problem??? It has nothing to do with sexism. Go ahead and support men we aren’t stopping you
