I used them.. and he called them a "hyper partisan website" ... when I explained what they were a 501(c)(3) nonprofit public charity that's when he came back and said TPM was the same thing..
I used to use ProCon as a truly non-partisan source on the muche. Which they are. They look at both sides of an issue withouut judgement. Nowhere have I seen or heard of them being anything else but that. Neither are a "charity", so I don't understand
L that comparison. As I said before, TPM is a left leaning news site, not a 501c.

ProCon is a research tool, not a news (or opinion) site.
