That would really bother me, the assumptions in both cases. Because they sound very much like stereotypes. (If, with the parent thing, she'd said something like, "Oh sorry, for some reason I thought you'd said they hadn't gone to college" and seemed genuine about it, then...maybe?) Also, she shouldn't really be bringing up politics like that (the comment about Trump). And she shouldn't be telling you to drop out of school, either. I mean, if you were saying, "I think I need to drop out, but I worry I'd seem like a failure," and she said, "It's OK to drop out," that's one thing. But it sounds like she's suggesting it on her own. She just seems to be overstepping her bounds, in addition to being a bigot with stereotypes. I'm not even sure the "micro" part of the aggressions qualifies there... I'd look for a different T.
