Bit of a weird reception this. Far as I can tell, there's no suspect motives going on here. Sounds like a genuine person. If she starts making injokes that only long-time posters would come up with or something similar, then maybe I'd be suspicious...
As for the actual topic: People in an area are being 'forced out' by new arrivals. This happens everywhere, but the 'dividing line' is not between white and black, but rich and poor. Unfortunately, due to hundreds of years of pretty standard human shittiness, white/rich and poor/black are statistically related. Seeing as there's still plenty of that shittiness around, a problem that has its roots in money and capitalism is worsened by racism and suspicion. Vicous circle
