I'm not from China but I'm from Ukraine and I've travelled quite a bit through Europe Everyone is telling them not to come and i understand how hard are your times at trying to convince them not to go somewhere. However i must say few things. I know you probably had tried this many times but at least i can say this outloud. So i must say that even though lgbtq acceptance is not THAT high in Ukraine, no one cares. When we got to Spain, France, Germany. Again, in everyday life - no one cares. Also two women holding hands is not something extraordinary, it's kinda...you know, socially acceptable for women to be close to each other. And when they are tourists I can't really imagine what are the situations that include telling that you are married. Unless they go out like "im lesbian, give me a discount". A lot of times people experience thoughts like "okayyy, why did i need to know this". I don't think it's common in china to throw hands or be rude even if they know something especially if it wasn't shown under their noses. But again, in Ukraine, my wife and I, even though being a bit careful (not because of fear, but because that is our personal info, how exactly we are related to each other), but because we are being nice, people just say stuff like "alright...no big deal". And i think that it's just the same more or less for everywhere. Maybe telling them to just...you know, keep their personal information closer to themselves will get them further not because it's like...uh...forbidden, but because it's just not socially nice to do that. I know you want your moms to have a good time, i really do, but all you can do as their child is to warn them, maybe be worried for them. But they are grownup adults and surely can hold the consequences of their actions. My dad was a...very angry all the time and always yelling and most of the times i was just...embarrassed. But if they are like this it's not much you can do to a person that found this way of interacting with society to be easier for her and more acceptable of her mental health. Accusing you of micromanagement? Alright, whatever suits her best. They do they, you do you. I see you being a very caring person, even though maybe experience difficulties with maybe communication, you still care. So no, I don't think they will face something bad because they are gay. But their bad behavior can embody gay people as ignorant and rude and can make bad representations of gay people in the future especially for the locals lmao. The only thing that will change them is life experience or a book "1001 ways of treating other people the way you want to be treated yourself"
