I feel like a lot of people focus that Aziraphale knows Heaven isn't perfect, but I don't think that changes that he still feels obligated to Heaven and how important being an angel is to him and how he applies goodness as an godly trait even to Crowley

Feel like this bit of the book is so telling

And I'm not even just assuming she misinterpreted the OP, they literally edited their post to clarify so people wouldn't misunderstand.

Oh, and the reblog you think is Aziraphale hate.

Let's take a look at another of their reblogs which is incredibly positive about Aziraphale.

Have you considered that someone not liking a certain action isn't hating the character and thinking they're a bad person?

And if you want to cherry-pick one reblog, what about these ones which aren't critical of Aziraphale and presumably take the meta as OP intended?

He wanted everything to be perfect so bad when he swept Aziraphale off his feet with his romantic little celebration and asked to put a label on what they both felt

The lapel thing isn't really a hard and fast rule - Beelzebub's lapels pointed upwards even in S1 same as Crowley's.

Aziraphale's lapels point upwards in his 1941 coat, Crowley's do not point down though to contrast it.

What's true to contrast their signature jackets does not apply to everything.
