I’m glad I’m not alone in my feelings! There’s nothing wrong with the smut, it’s just not for me. I wouldn’t call the fandom to suddenly stop what they’re doing and become completely PG, but working on not consuming the same level of smut is something I have to do for myself. This is all about personal preference and what we are individually comfortable with, so we are each responsible for filtering our dashes for ourselves.
Something I forgot to say in my tags (that I know others are saying too) is that book boyfriends aren’t inherently bad. Like you, I prefer to focus on the emotional side (fluff and angst), and so that’s what I imagine with a book boyfriend. I don’t think there’s anything wrong with imagining the sexual side as well, it’s just my preference.
So far the fandom has been great with respecting people’s preferences and comfort levels, and I hope that can continue without any meanness.
