I hear that sentiment from a lot of right wing friends in US fwiw. IME here it's more a coded speech and / or an escape from difficult conversations. The coded speech part steers it towards general conspiracy topics, which are often a simple way to blanket discard everything "liberal".

An actual example: "What did you think about Bill Gates climate book?" (they'd read it) -> "He was associated with Epstein, he's a creep. I don't trust anything he says". Then, "What do you think about Trumps delaying and denying of Epstein associations" -> "There's so much back and forth, who knows what to believe."

To be clear I think your take is correct, its just I think that if the space were saturated in a direction that were more convenient towards their "team", they won't have much difficulty taking a clear stance.
