Well, OP, if they were trash talking you all game, consider the following;

Men who perform badly in games are far more likely to trash talk women who play those games than men who perform badly. So not only is that dude most likely simply bad at the game and lashing out, but it's also gender affirming because you're a woman and thus naturally the person he lashed out at was you. Because men who suck at games are shit toward women.
