No I'd not forgotten, but science and scientific opinion evolves, if it didn't then we'd still be sitting here believing the sun rotates the earth, and that you can cure virtually any illness with leaches. People are entitled to their own opinions for sure, but whether that extends to peddling lies at demos in Berlin and London, and making patently false claims about vaccination, 5G causing Covid-19 and the like and the like I really am not so sure. I'm not suggesting anyone posting here is doing any of that, you can be sure. Nobody here is that stupid / devious.
