To everyone , to black , white , green or purple ; should a man hit a woman?

This is not really a question nor comment but my true opinion. I am making my judgement from past incidents and newly hollywood incident between Rihanna and Cris Brown. Many people say that Rihanna is not a sweet angel and that she is truly jealous female . As a matter of fact she has a tendencey to hit men. However I am not saying this is what happen in her case but I truly believe she is not 100%innocent. Regardless of who hit who its a shame of that got that crazy/ However , not just Cris Brown but other ordinary men that I know treated unfairly in domestic violent cases because they are the men . Many times what I witness the female provoke , or even aggressively attack the ma n like she was a man. So what if a female provokes , or aggressively attack her husband or boyfriend should he just stand their and get his whoop . Or should he protect himself?In my opinion if a women has the enough to step to a man like she's big and bad and lay hands on him like she is a dude .I feel that female should be knock out like a dude by the dude. Or if a female tries to provoke a fight with a guy I feel that guy should put her in her place not by hitting her; unless she hits him; but by putting her in her place. I just feel that there is a line to draw , and many times females know that the justice system is 90% of the time on their side when it comes to domestic violence regardless if she is the one who provoke or attack the dude. I just feel in certain cirstances a men can not when or lose when it comes to the justice system especially in domestic violent case . To many times I have seen both ends of the specturm . I have seen a controlling , scary abusive man who earns his rights to go to prison. However ,I have seen females putting their hands on real man who tries his best not to hurt the girl but sometimes he just have to defend himself . So do ya think iits ok for a man to put his hand on a woman when provoke or defindeing himself ?
