Do boys see girls who lose fights as losers?

The ones who do see you as losers are probably losers themselves. Don't like the idea of calling people losers. It's probably one step removed from being called a slag.
Ideally don't get involved in fight situations but it isn't always so easy.

I don't like to see girls fighting, I think they should all bond together like one great big sisterhood, therefore if two girls fight each other they are both losers as far as I'm concerned.

You are breaking the rules ,we don’t talk about fight club

Fighting is meh. Gets boring with age. So nah.

Definitely.

Nope
