That’s not equality.
That’s more along the lines of domestic violence.
Why is it that “equality” is supposed to mean men can hit us WHEN MEN ARE ALREADY HITTING WOMEN AT APPALLING RATES???
Literally the only situation which men and women should be allowed and encouraged to get physically rough with one another is if they’re playing contact sports (or during consensual rough sex, but that’s a different story). Do if you’re asking “does equality mean my boyfriend can tackle me while we okay football because I tackled him”, then yes. Yes that’s equality.
But if you’re saying that equality means a woman can physically attack her boyfriend, and her boyfriend has permission to fight back, you are nowhere near the same ballpark. That is an entirely separate scenario and you clearly don’t understand the depth of the issue.
