I have worked on some labels to put on lefties.
1. "climate magnifiers" when they talk about climate change
2. "scientific manipulators" when it come to gender, covid and anything they support that contradicts science.
3. "conspiracy deniers" specially when its proven that a conspiracy theory is actually real.
4. "race supremacist"
5. "fact deniers"
6. "fact oppressors"
just some thoughts lol feel free to use them specially if you have any type of publication.
