double standards in this case?

Ja
If a lady/ woman is being attacked by another female, is it okay for her male partner to jump in and use physical force to stop the aggressor? Even if it means throwing blows at her? Of course if it were a male, everyone would be like "Yes, of course, he should always protect her from danger!" But if it was a female, would the situation be different? Bc as it goes "A man should never lay his hands on a female.", so... what about now? I mean I don't think anybody should be putting hands on anybody for that matter, if we all handled our issues civically we wouldn't have this problem, but obviously that's not how our society works🙄 anyway, what are your thoughts?
