Yes. I think a man has every right to protect himself against a woman if she is physically abusing/attacking him.

Yes, when she throws the first blow. My grandfather said "If you're big enough to throw a lick, you're big enough to take one". Everyone needs to keep their hands to themselves.

Yes - if she hits him. Men aren't punching bags and I for one do not expect a bloke to stand there and get beat on by a woman just because she is a woman

If that woman is running at him with a knife or is going to try and hurt him physically in some other way, then sure, it's acceptable.

Its acceptable if woman deserved it otherwise its sexist not to hit a woman

what if shes stabbing him with 2 knives and kicking him?..

only when he doesn't get a sammich.

Absolutely

Self defense

No man should ever hit a woman, unless defending his life.

There are an infinite number of such instances. Would you care for an example?

Is there any instance when it's acceptable for a man to hit a dog?

I think it's okay when it's in self defense and the crime equals the punishment. Iykwim

We are all one ,there is no weaker sex so it's fine in my book

No, nor a woman hitting a man either.

Yes. Right before she stabs or shoots me. No other reason.

The only one would be in self defense

If it’s the only way to stop [b]her[/b] from physically harming him.

Yes

HELLLLLLLL NOOOOO!!!!!

Not that I can think of.
