So if you were a "lefty" all your life, then when and why did you suddenly decide to be so tolerant and condoning of racism and antisemitism and misogyny, and decide to start spreading lies in support of violence and hatred?

You know you're lying too, and you're not arguing in good faith, just gaslighting. See my reply and dataloper's reply to Duckfeathers, because it also applies to you. You've demonstrated that your arguments are insincere and deceptive and not worth responding to, because you're a liar.
