I don’t want to take over some random 18 year old’s post but I do legitimately wonder how to make sure anyone I’m in a long term partnership hasn’t drunk the anti coolaid.
My personal advice is to make that part of the “getting to know you” early dating stage of the relationship.
It’s easy, casual and normal to talk about what type of fiction a person likes and dislike, and what sort of attitude they have toward censorship, and toward fandom.
You don’t want to lie about proshippers in public because you know they will come and correct you?
I don’t normally post discourse here, because this is my weirdo zone (where I am weird uninterrupted.) That though is exactly why I’m responding. I always see shit like this and sit there like: bruh I am literally just chilling. I am vibing. I am a big, nasty proshipper, and I am literally only aware of you through responses like OP’s. Nothing will come of it, and I will forget you exist in a day or so. I will simply go back to sitting in my corner, playing with my blorbos the exact same way I played with my bionicles as a kid: with reckless abandon.
There will be people to correct them! Indeed, OP could be one of them. Yet we aren’t this hivemind of discourse. I am not coming to get you. If anything, I’m hiding more tightly in my corner, like avoiding schoolyard bullies.
