Half of my family is conservative, watches only fox news, and considers all liberals to be "wrong about everything" because they have an entirely different set of basic facts about the world, different heuristics, different opinions, different ways of confirming those opinions, different understandings of fundamental topics, etc. Any time these two groups have a conversation it will probably feel like gaslighting because if you have any thought that relies on any base assumption, they will deny it and claim "that's not how the world works" and insist they know how things "actually work" and you will not be able to convince them differently even if you could demonstrate things right then and there.
If you are unwilling to accept scientific discovery as a significant indicator of something, then no amount of scientific work will convince you, and will just feel like someone trying to disprove your entire world view, while if you are unwilling to accept ideology and dogma as significant influences, you will feel like you are taking crazy pills as a large group denies reality in front of their very eyes
