This is not objectively true but I understand what you're trying to say. I'm sad to hear that your experience of science and truth has been only that which society has given you, or at the least that you feel that others are only experiencing it in that way
A lot of it is like Bostrom's idea of the decentralized electroshock dystopia: even though a significant proportion of people are witches, everyone's afraid of reprisal for not actively hunting witches, so the witches-in-hiding hunt their own when they're unmasked.
But this is the way of things; this wave will pass, eventually, as well. And like the soviet scientists who kept their heads down and mouthed the party line, the secret iconoclasts will survive till the current order is replaced by the next, with its own peculiar tabboos.
The short summary is: Two people sitting in a bar, discussing how there is no objective truth, or that "science or truth exists only at the whims of the social order" and stuff like that, all day long. And then a third person comes along and smashes their brains with a barstool. In some variations, the first two people are a scientist and a priest. But the third person is just some dude with a barstool.
