Fairly often I encounter situations where someone is, in my mind, obviously lying. Their point is incoherent or conflicts with a lot of other statements they made, and in order for them not to see it, they'd have to never have even thought about what they are saying, not even one second.
An example I have is someone who explained to me that homosexuality was bad because it was narcissism, you're in love with someone who is like you, that's just like being in love with yourself. Obviously this logic doesn't work: in order to live to the standard of not being a narcissist, that person would have to date a disabled trans black woman who doesn't speak french and hasn't grown up in Switzerland, which, obviously, he wasn't. But to me it is inconceivable that this person doesn't realize that, so my mind cancels all of that reasoning and hears something like "I hate gay people" instead of what was actually said.
I've come to find out that people don't like it when I do that. It's divisive. When I question that person's honesty in describing his feelings towards homosexuality, it is somehow worse than if I had assumed that he was making one of the most insanely illogical points I've ever heard, seriously.
I used to think that it was a failing of mine, because I tend to apply this principle pretty liberally. This example that I gave is extreme, but I often assume dishonesty rather than irrationality. But I don't really know anymore. I think this is also tied to civility politics in a way, where we all pretend that we believe in the same principles in order to achieve living in a society together.
My honest belief is that this person thinks people who have a different sexual orientation are less human, but he can't say it because that's politically incorrect so he has to make up a stupid justification for why he hates them, instead.
Living in the world that I live in because I believe that isn't always fun. It's probably more comfortable for most people to live in a society where people have terrible logic than to live in a society where people have different moralities. I wonder how much of that plays into the perception that I'm being offensive, and that if I just pretended to believe they're intellectually incurious enough to believe the shit they say, I wouldn't be.
