I'm not against shipping too but I noticed that if two guys of different group(or one of them is actor) hanging out together there would be comments like" what a cute friendship"(which imply that 2 guys can't be a couple). If there are 2 guys of same group who are shipped with each others often, there would be comment like " Vkooook or Jikooook or Chanbaeeek" If a guy idol and a girl hanging out together "they are dating"
That why shipping is not taken seriously because people often ship not because they think one of them likes males but because they think "they look cute together". I saw once someone here saying that shippers usually said " he is gay for******"and not think about his true sexuality, which is true sadly.
