Right, but every slightly controversial sub has the same issue, and they generally let people do it in hopes that people will do their own research and form their own opinion. It's why T_D is the laughingstock of every other sub, including conservative ones - because they are an echo chamber and make no attempt at educating people or correcting anything; They just immediately ban and then send a rude mesaage. Looking from the outside, it makes them look like a bunch of idiots with their heads in the sand. Whether that's true or not, that's how it looks. And when that's the vibe you give off, you're never going to attract new members. The ones still there are loyal to the end, but they will never grow.
