a "who started with who" game is kinda irrelevant IMO
both were online looking for and engaging in mess. Throwing shots on albums, throwing shade, arguing with other rappers
After a certain point adults have to take accountability for their behavior regardless of who "started" with them. That excuse is for kids not tryna get suspended from school for fighting on the playground.
Or in some cases a valid defense for defending yourself against serious bodily harm. Not for spending hours on Twitter arguing with people pretty nastily, when you don't have to. You choose to do it and it's up to you figure out why you make that choice and can't walk away.
