I never understood why people think frans is pedophilic. Sans isnt an adult in the game hes a teenager, and we dont actually know how old frisk is. We assume child but child can mean any age, in any case sans is the same size as them. It seems pretty weird to think its pedophilic in any case, your art clearly portrays them both as adults. Sorry you got that ask.
funny enough, when i first played undertale i never had a specific age (or gender/race for that matter) in mind while playing frisk. same with sans for that matter. i didnt even ship frans until i saw fan art of it featured here.
i think the core in antis thinking process is that they head canon frisk as a child, and when they see frans art, they dont see frisk of the age that the artist has interpreted them as. they just think “frisk = child = pedophilia” and then they call the ship toxic and tell shippers to kill themselves, and wish death and harm on people that have done nothing wrong. and then they pat themselves on the shoulder for making the world a better place :)
