You honestly haven't been a very generous or curious discussion partner (and here I thought you actually wanted to know why "tankies" believe what they do), but any revolutionary worth their salt should never stop studying and struggling with others over matters of ideology, and to that end I ask you to, in future discussion, try to understand where people come from when they engage in good faith discussion and not make caricatures of their views and then stone-wall. There are not blood-thirsty "red fash" in your midst.
