I wonder how it will change conversations on here and if the negative responses create or reinforce geographical (and inherently racial) biases.

It has for me. Not FROM me, i don't care where people are situated, but TO me, i'm Australian but my browser uses proxies from Norway, but some don't seem to get that and have accused me of lying. It's bullshit, now i gotta think twice about the threads i take part in. The thing is, if i google my ip it shows up as a proxy so why they can't have a proxy flag i don't know.
