You are saying that Progressivism on TYT is an entirely different type of progressive than normal. Now I can't speak for everyone on this site but I'll take a guess that you don't have evidence that everyone here believes in the principles you stated.So I think branding a entire web site of people in that way isn't the right way to go.
More to the point what does that have to do with Cenk not being progressive. If you agree that it isn't mutually exclusive then how does that make Cenk not progressive?
