Disclaimer: I abhor violence of any kind and would never advocate it or excuse it.
That said, I believe she's quite capable of so enraging folks that they resort to violence against her. Bobby and JA did coke together. Coke + a maddening JA might well have led to choking her. Saying FU to her father in every way she could no doubt made him extremely angry.
She drove Travis to send a text filled with thoughts and language that by all accounts were otherwise foreign and distasteful to him. But the measure of his self control, and of his complete innocence on the charge of abusing JA, can be found in how he handled his rage towards her the day she confronted him about what she saw when she tiptoed into his yard, uninvited, and spied on him and whatever woman he was with.
According to JA, his response was to walk away from her , then to bang his head against a closet door.
Doesn't that say it all?
