this is from a whump blog, ma’am you literally beat fictional characters up.
having underage f/os doesn’t make you a pedophile, sexually assaulting and sexually thinking about REAL CHILDREN does. also no one has to constantly paint problematic ships as harmful and evil, to KNOW THEY’RE HARMFUL IN REAL LIFE.
YOU of ALL PEOPLE should know that writing about things that are bad, DOESN’T MAKE YOU A BAD PERSON.
Imagine your F/O taking you on a classic Valentine’s day date. The two of you get dressed up, and they take you to a gorgeous and fancy restaurant where they made reservations. They have chocolates and roses for you, and when the two of you get home, the lights are low, and the setting is perfect for an evening alone together.
Just like you said “Is there any proship statement that says something like “shipping canon straight characters with same-sex partners is just as valid as shipping canon gay characters with opposite-sex partners as long as you’re not a homophobic jerk IRL”
Fanfiction is fanfiction. It can never “taint” or change the original material.
You can ship anybody with anybody.
It’s not somehow wrong to ship a canonically gay character in a straight relationship, any more than its wrong to ship a canonically straight character in a gay relationship.
Fanfiction is your playground.
Nobody should be telling you what to do.
If they don’t like it they shouldn’t be reading it.
