Progressives don't want conservatives and libertarians to form their own communities, unless maybe those communities were poor (it could possibly help with their egos in that case.)

Conservatives may stereotypically complain about welfare, but I'm pointing out how gentrification can benefit progressives who want more integration.

Some people at /r/srsdiscussion must be truly pro-censorship, as they had a comment removed which explains a conservative view on "affordable housing" and gentrification. Here's what was said:

I am a conservative on this issue. I don't like it [gentrification] because it changes the demographics of communities further away from the city , as the former city dwellers move into the suburbs. (lowers the average value of homes too, usually). I don't know if this issue is well known enough, for there to be an "official" liberal / conservative stance on it. I've only read some of this book a while back, but there is a book called Spreading the Wealth: How Obama is Robbing the Suburbs to Pay for the Cities.

I'm personally not saying that Obama has much to do with it, that is the part I don't know yet. When making the connection between the left and gentrification, a big part of the logic could be backed up by statistics and your own observations if you live in a good sized metro area, as I do. Is suburban poverty noticeably higher than what it once was? Yes it is. The US Census releases info on demographics every 5-10 years.

If you see an apartment building which has many units that cost less than $600/month, how pleasant do you think many of the tenants are? Gentrification is also only part of what makes it all happen. There are laws which say that "affordable housing" must be everywhere. Depending on where you live, at least, apartment owners probably can't discriminate against section 8 tenants.
