Because I always get my news from YouTube. You can't put it on YouTube if it isn't true. Views expressed on YouTube reflect the entirety of reality.It is not my fault that you don't look at leftists on youtube and see what they believe. Perhaps I should call them "radical leftists" but yes the radical left wants all these things. There are leftists who aren't THAT FAR left but they agree with most of the same goals.
There are leftists on youtube and right-wingers. I watch both. These are REAL PEOPLE. How is it wrong to say that real leftists are advocating for this stuff based on what they say on their channels and based on people agreeing with them in the comments? This is how an instant communication society works.
