I see that you frequently employ laughing in discussion, that you are pretty confused about different ideologies (such as seeing communism as being inherently authoritarian), and that you are frequently sarcastic and dismissive to others. You consider anybody suggesting change outside of capitalist philosophy as radical and you mock others for blaming capitalism for their problems. I apologize if I'm mischaracterizing you, I quickly skimmed a few pages.
Be respectful, debate in good faith, perhaps stop typing your laughs and other perceivably rude remarks if you don't want backlash. Or just do you - you are allowed to have gripes with various systems and ideologies and express them and discuss them with others.
Pay less attention to the downvotes. The downvotes don't hide your comment as on Reddit. There is also no collapsing of comments done by mods. Myself, I'm personally not a fan of the upvote/downvote systems and if I continue using this service I'm likely going to zap the upvotes/downvotes and all vote counters with uBlock Origin (as I don't participate in voting anyway).
I'll keep an eye out. I have been using this website moderately for nearly a year. I'm sorry your experience has been different - not discounting you.
