There is no invalid reason to ship something
You ship them because you like their chemistry? You good, keep being great.
You ship them because they look very cute and/or hot together? Man, me too.
You ship them to cope? That’s amazing, I’m proud of you.
You ship them out of spite? Hell yeah.
You ship them because you want to explore human (or otherwise) relationships? You probably are a lot of fun to talk to.
You ship them because you project yourself in one of the characters? Go for your dreams, darling.
You ship them because why not? Crackshipping has been around for a long time, if someone tells you that it hasn’t they’ve probably haven’t been in fandom for long.
You ship them for literally any other reason? Perfect, go wild with it, no one can stop you.
There is no bad reason for shipping, no matter you motives you’re just having harmless fun. No one has the right to stop you from exploring fiction as you desire, it’s your desition and yours only what you want to do in fiction.
Keep being you, lovely ʚ♡⃛ɞ(ू•ᴗ•ू❁)
