It reminds me of an exchange between Neil Degrasee Tyson and Richard Dawkins in which Neil tells Dawkins that, while he makes good points, perhaps he should soften his delivery? Because it's hard for the realm of science to pull in new defenders when their staunchest proponents are telling its detractors they are imbeciles. And dawkins fires back with [...]"Science is interesting, and if you don't like it, you can fuck off". EDIT: This exchange must have been in the mid 00's? The birth of the Four-Horsemen-of-Atheism era. The absolutist cultural debate position has a rich history.
There's a time and place to cut ties and not waste time interacting with people that disagree with you. Sometimes the right move is to reject an ideology or group outright. But it seems like the modern concept of that time and place is very skewed.
