I appreciate the context abt the situation in China. I didn't realize how much weight that 'betrayal' narrative carries there or how personal this is for you and your marriage. It makes sense why you feel the need to push back so hard.
Abt the bi stereotype, I think in my country, some ppl I observe have the same mindset as that too, even though it's not extreme in this situation, they think that "bi ppl just have an easy way out compared to gay ppl, they use gay ppl for a phase/experience, ...".
It's just like one poison apple in a basket full of apples, which make the ppl to reluctant, whether they want to eat the apple or not. Or in the bigger picture, it's like straight ppl agaisnt the lgbtq+ community.
This topic alone is really complex and can't be discussed through some texts, both side have their own reasons. Even I don't know how I would react if one day my same-sex bi partner decides to break up cuz they want to be with someone who can have kids together. But I know that attacked ppl just because you have a happy marriage life are never right.
At this point, the drama is just about them being negative for no reason. It’s clear you’re staying true to the M/M focus while just being honest abt who the characters are. Like I said before, the best way to prove them wrong is to just keep dropping high-quality M/M updates. Actions always speak louder, and you can't be popular with fans without some drama and haters after all.
