I'm feeling feisty this morning and maybe a little out of my mind. I didn't read their comments but I personally don't think hitting a women is any different than hitting a man and I'm anti-hitting anyone for the most part.
All that being sad, some people (men and women) get out of control and start acting a fool, saying things and doing things that purposely pushes peoples buttons, when acting that way they shouldn't be so naive to think their actions and words aren't going to bring about some consequences. Point is if you really don't want to get punched in the face there are some things you can do or avoid doing to help keep this from happening.
Maaaaaybe can see this with a slap. However, I can see no circumstance where a person says something worthy of a full on Mike Tyson's Punch Out uppercut in the middle of public, especially when said person has no chance of fighting back.
