Is it ever okay for a mother to slap a teen so hard they bleed?

I don't have a close relationship with my mother. I still remembered (I was 16 at the time) that horrible argument where she slapped me too hard enough to draw a bit of blood on my lips. She was saying bad words, getting in my face, being antagonistic and I only replied saying shut up and she slapped me like that. Then she had the nerve to say "Don't ever say that to your mother, got it".

Needless to say this only further infuriated me (I saw red at that moment, I beyond angry), making me scream louder than ever and I shoved her against the wall. I was closing my fist, about to hit her back but stopped at the last moment. My grandmother (mom's mother) took her side instead of at least being neutral.

I don't visit her too much. It makes me angry when people think a mother can slap teenaged child that hard enough to draw blood and how dare the teen reacts towards getting assaulted.

Off course I'm going to react with anger too, after getting assaulted and bleeding. No, what she did didn't make me calm down at all. It made me more violent.
