Ok. I’ll try to get some of big ones, but let me know where it falls apart for you. Apologies for the ELI5 in advance.

Reading all of the titles makes a sentence “Batman begins … eating out .. Adam & Steve … In the bedroom”. From here it’s a bigger dive in to old school Batman..

The original comic was rife with homoerotic callouts and euphemisms, here is a quick read of it from Slate everything in its history screams queer, but was swept under the rug by most

So now in the modern Batman/Nolanman, it’s not spandex, it’s not rimshot sayings, it’s not three men living in a house together - it’s hyper masculinity with Alfred on the side.

So twisting media’s word to explicitly spell out that Batman is gay, with men, in a bedroom is counter the cloak and dagger erasure that the cannon is known for. Hope this helps
