Anon asked: Where is the textual or subtextual support for Tyzula? I know people point to Ty Lee constantly praising Azula and their interactions at The Beach (alongside Grey's and Hack's headcanons) but couldn't those actions just be interpreted as them being friends or Ty Lee making sure she stays on her ill mannered sovereigns' good side (this is what the comics explicitly say)? But if you think Tyzula happened during the show and/or pre-canon, how do you think it worked? Do you think Azula was a good girlfriend or just completely abusive? Or something in the middle? And post-canon do you think it could be rekindled after Azula changed herself or Azula and/or Ty Lee would choose not to in light of their fraught history. Or if you think it never happened in canon, but they have UST, do you think, in the post-canon era, they had a relationship once Azula changed, became fuck buddies, and/or just fucked once to get it out of their system? Or again they choose to not interact with each due to their fraught history? And if word of Tyzula ever came out to their friends and family (including Ikem and Kiyi), how do you think they would react? Also, do the comics change any of your answers? How do you think their relationship was affect by the homophobia present in the remaining three nations (including the explicit persecution and stigmatization in a post-Sozin Fire Nation)? Do you think FL Zuko changed the laws ASAP or only changed them after seeing and hearing about Tyzula? Or he never changed them due to his homophobia and/or disliking Tyzula? And please feel free to touch on things that aren't covered by my questions. Thank You!

While you are right when you say that the constant praise Ty Lee gives Azula is a form of self-preservation, you need to keep in mind that fear of going against the crowned princess wasn't the only reason why Ty Lee was friends with her. She did genuinely like Azula, and that was one of the many things the comics retconed. I went on more detail on the friendship between Azula, Ty Lee and Mai on this post: post/651284858615824384/what-do-you-think-was-the-basis-of-mai-ty-lees
The main reason why so many people see Tyzula as a very real possibility is because of the chemestry between the actresses and because of the accidentally flirty vibe many of their scenes together give off. For the longest time I couldn't even stand this ship, but even I was like "Oh yeah, there's no heterosexual explanation for the way these two talk to each other".
I don't think it ever happened pre/in canon. If it had, I think would be a weird mix of both a healthy, loving relationship, and a completely toxic dynamic (just like their friendship was).
If it were to happen post-series, Azula would need to redeem herself first. She'd need to prove she was at least trying to get better for Ty Lee to decide to willingly interact with her (but she wouldn't wish her any harm even Azula never felt sorry for what she did, I cannot see happening at all). Once they were as close to each other as they used to be and Azula felt emotionally ready to have a romantic relationship, I can see it happening and I think it'd be a healthy romance.
Assuming the Fire Nation really was homophobic and had laws that discriminated against gay people, I can totally see Zuko changing said laws during his first week as Fire Lord, as I think he'd be both a very tolerant ruler AND be too busy dealing with actual problems to even think about disaproving of any consensual relationship. Ursa and Iroh could act a little awkward at first, but they'd get over it quickly. Ozai would be pissed, but only because he knows other people would disaprove and think of Azula's sexuality as another reason to shame him. He doesn't care about "morals" or whatever Azula does of personal life.
Kiyi and the Gaang would be okay with it. Inanimate objects don't have opinions, so Ikem would have no opinions. Kyoshi was bisexual, so it's safe the say the Kyoshi Warriors would be supportive. Mai had known this day would come a loooong time ago and is just suspicious of it because she's suspicious of Azula's intentions (she'd get over it).
