Ok I just need to say something real quick
A headcanon: Something you believe a character to be, usually gathering context from a series to support it (unless its something random or silly)
Actual canon: Something confirmed by the character or writer
People who pull a bunch of evidence from Homestuck to “prove” Dirk Strider is 100% just flat out gay: That is your headcanon. Not confirmed by AH.
Just because your headcanon is popular does not mean its canon.
Except that this is incorrect and Dirk is canonically gay. “Considering our respective orientations, Jake was the only viable romantic target,” said BY Dirk. You have to do some pretty impressive backflips of logic to interpret that as meaning anything other than “Dirk Strider is gay.”
There’s a fucking boatload of other evidence, including, to fulfill your writer confirmation requirement, Andrew Hussie getting as close to stating that Bro was gay as he gets to stating anything, which if you believe orientation is innate would also apply to Dirk. But you can throw it all out, look at just that one quote, and there is literally no way to interpret it as anything else.
This annoys the hell out of me. Why do we need to have Dirk wave a rainbow flag and shout YES I AM A KINSEY 6 HOMOSEXUAL before we’ll finally allow the one gay male in Homestuck to not be intensely fucking scrutinized????
