I agree, the weird thing is that this view seems to be changing among leftist people. I live in a very leftist area in a leftist city in a leftist country and the past ~5 years whenever the topic of age difference has come up among people my age (35) or younger it’s been increasingly “they’re both adults, nothing wrong about it”. And I just can’t agree, it grosses me out and feels wrong in the deepest parts of my soul. Yeah, they’re both adults (when it comes to the youngest being 18+) but that can’t be the only thing that decides if it is or feels wrong.
