generally speaking, a pro-shipper is someone who doesn’t judge what others ship, which sounds innocent enough except pro-shippers often ship or defend ships w/ incest, pedophilia, abuse, and so on, glorifying or romanticizing these concepts. i’ve seen quite a few of them claim there’s no problem w/ these ships or shipping dynamics bc “fiction doesn’t affect reality” which is…so unbelievably not true!!! so yeah i just don’t really like the “enjoying pedophilia is ok as long as it’s fictional characters” crowd and would prefer for them to stay far away from me and my stories. hopefully this explanation was coherent enough lol
