This seems straightforward. You posted your opinion (which is inherently true - no one but you has access to your inner mind, so we must take it on faith you are honestly presenting your opinion to us) and the mod misrepresented this as fact so it could be labeled as misinfo.
But I doubt posting here will fix that. Mostly what you seem to have managed is to attract genocide supporters from Hexbear to troll you. As I understand it, the best way you can handle this on Lemmy is to simply find similar threads on a different instance to engage in discourse in.
