Exactly, and for anyone saying MMOs are always like this I say you obviously never played City of Heroes, which had an active mod team that helped create the most welcoming and helpful community, gaming or otherwise, I've ever experienced online.
Also ignore and move on really isn't a solution. Yeah, you can't see them any more, but everyone else can, including new players; how exactly is that going to help draw new people in to the game?
TL;DR - Chat doesn't have to be toxic, BioWare simply need to start enforcing their own rules.
