“All of Germany, and I haven’t met one Nazi yet.”

I don't think anyone here is trying to force Under Armor to do anything, or arguing that they would be able to do so if they tried - no one is talking about getting the city involved. UA is free to do just about whatever they please with their property, this just seems to be an earnest appeal to them to not sell it for development. It sounds like it's a nice thing for the community and I hope that they're able to retain it in some form.

I don't know that it tells us anything about the sub's politics. Based on where it tells us users live and spend their time, I'd go so far as to say most are white, but it doesn't say anything about that definitively.

I think what that map does tell us is that users overwhelmingly live and spend their time in the affluent neighborhoods in green on the Niche map. More importantly, though, consider all of the discussion in r/baltimore on the problems facing communities in the east and west of the city. I think that that map is evidence that users overwhelmingly don't visit those parts of town, most of them ever, which calls into question how useful their perspectives are.

Like, people in this thread are calling this a redlining map, and that could be very true, but have you tried mapping out where you spend your time and money? Evidently, it might look just like this.

Based on r/baltimore's recommendations for local businesses to go to from this post two days ago, it sure looks like this sub concurs with these ratings.
