Your experience there doesn’t surprise me in the slightest. As the mistake you made there, was that you assumed that the truth would somehow make a difference. They lap up ****e like that without question, as they want to believe it, as it reinforces their existing prejudices, being offered the actual demonstrable truth is therefore of no interest.
The same sorts grab hold of any fig leaf handed to them in order to dismiss entire topics that they don’t want considered. For example, I’ve lost count of the number of people on social media when trying to pretend they’re deeply offended by the removal of a statue of a slave trader they’d never heard of, in a City they’d likely never visited or are likely to, have lobbed in, yeah but what about the pyramids though, when are they ripping them down! As if it’s some sort of zinger, when it has no equivalence whatsoever and is merely irrelevant whataboutery, but the thing is, it doesn’t matter, as it’s given them the excuse they needed to dismiss the entire debate about us having commemorations of actual slave traders on our Cities streets in 2020 ffs.
These kind of people have seemingly enjoyed being lied to by the likes of Trump and Johnson, as long as it upsets the ‘libs’ it’s all gravy. The thing is, once your start accepting and applauding being lied to by politicians, then don’t expect it to stop, only one day they’ll lie about something you don’t agree with, but it’ll be too late......
