You haven't read my comments, have you. </rhetorical> I'm going to type it bigger so it'll stay in your memory.
BOTH ARE AT FAULT.
She should not have taken the phone. He should not have reacted so violently to her taking the phone. It was a PHONE for god's sake, not the freaking Holy Grail.
SHE is at fault.
The guy simply retrieved HIS property.
You're trying to salvage the woman here. SHE'S the one at FAULT. SHE took/stole HIS phone. If SHE hadn't done this, no physical altercation would have resulted.
This seems to be a 'Sexist' argument. You're trying somehow to blame the Victim. You know, the guy that got his phone taken.
