Fictional influence reality?

I had an argument on tik tok and basically I said the sexualizing minors is wrong fictional or not. Then they brought up the "but you watch dark themes so you shouldnt be talking" but the video got taken down so I couldnt refute. What do yall stand in this argument and why?
I can give more context if yall want, like which animes they thought were just as bad as loli hanime
