I mean, maybe we're getting to the crux of your lack of understanding of the insult then. Every insult ultimately relies on the idea that the person doing the insulting doesn't like whatever trait they're framing in a negative light.
I did type a lot more than "I personally despise it" so it does feel like you're ignoring the majority of my points now. But that's how it always is, there's no objective good or bad, it's always gonna boil down to personal opinion if you dig deep enough into why you consider something good or bad.
You value "truth" so you'll typically think of things as good if they're true and bad if they're false, but I am curious now what your opinion is on things that are not debated on a basis of true and false. I don't have a good example off the top of my head though.
