Have you ever had an IQ test or similar? You sometimes get questions like “A car is to transport, what a fork is to ___” with the answer being “cutlery”. It’s not that transport/cutlery or cars/forks have anything in common, it’s about their relationship to the group.
So in the post it’s saying that “if you think paedophilla is just a type of sexuality, then murdering someone and burying their body is just a type of gardening”. It’s not exactly a flawless comparison, but that’s what they were going for.
...so I understand where you're going with this, but I think it is such a poor attempt on his part that I'm still trying to understand it lmao. I guess you're right, what else could it be really? Still makes no sense to me though.
Like I said, it’s not the best example but it’s also not the worst one of these I’ve heard, they can get really really obscure. Maybe this is a better explanation/translation:
“If paedophilla is as innocent as a “sexual orientation”, then burying your dead body in my garden is as innocent as “gardening.”
OH ok yeah your rephrasing here connected the dots, thanks. Hell it's definitely one of the dumbest I've seen, I do not envy you lmao. Thanks for the help on that!
