Hym "YET, still, here I am. My rights still being violated. My head still failing to drain the fluid through my lymphatic system. My bank account, empty. As my life's work has been stolen by billionaires. Waiting (patiently) for the warm glow of liberal morality to touch my life. And, while I wait, Palestinians die because you just NEED to take a hard line on Anti-Semitism. Our freedom of speech infringed upon because you need a nebulous subcategory of speech to which our rights do not apply and thus, the Anti-Semitism law. If you can do it, they can do it, so they did it and now our rights are diminished and it's entirely your fault. So, knowing better than God doesn't really amount to much."
