This wasn't a situation of a guy hitting his girlfriend or a random woman, this was in the midst of a larger street fight between two families. Not a good look, but I don't think the young man is out looking for women to beat up. He hit a woman who was hitting a relative in a fight.
From the original story.
According to Hairston, Taylor returned to her apartment on Thursday after she received a telephone call from her babysitter, who told her that Taylor's 9-year-old daughter was arguing with Simmons' 10-year-old sister. Hairston said that when Taylor attempted to leave with her daughter, Simmons and others beat on her car.
Hairston said that Ashley Bradley, another one of Simmons' sisters, then pulled Taylor out of her car and struck her several times, and that after Taylor was pushed to the ground, Simmons struck her several times with his fists. At the end of the video, another woman is shown striking and kicking Taylor. According to Hairston, the woman was Simmons' mother, Brenda Bradley.
"My 4-year-old grandson had to watch them beating his mother," Hairston said.
This is coming from the victim's mother, but if true it isn't remotely close to the situation you are trying to defend as Simmons and his relatives initiated the attack. At any rate, a 6'4" 275 pound man beating on a woman who is on the ground with two other family members attacking her is well beyond "not a good look."
Edit: Also, characterizing this as a "larger street fight between 2 families" is a gross misrepresentation of what went down. Only one person was involved from one of the families.
