Hi OP
I hope the derailing of this thread hasn't put you off from posting again.
There is lots of good advice on this thread already, but I just wanted to add my own perspective. Caveat: my children are not teenagers yet so I'll admit my lack of experience with this particular demographic!
It strikes me that your children and husband are disrespecting you in your own house by monitoring what you read and attacking you for your opinions. They don't see you as a 'full' person but rather as an extension of themselves and a facilitator of their needs. It's time for you to take back some control.
As others have said, make sure all your devices are password protected so they can't spy on you. Tell them to stay out of your phone and laptop. If you are reading any 'physical' books put them in your own room where they won't come across them. You deserve your privacy and it's wrong of them to invade it.
Secondly, avoid this topic like the plague unless you can be sure the conversation will remain civil. If they bring this up in a confrontational manner, then I would just refuse to engage. A non committal reply, a shrug or a simple 'ok then' is all you need to say. Do not allow them to call you names - if they call you a bigot, or hateful, just tell them that name calling won't be tolerated and that there will be consequences unless they apologise.
I believe that part of the reason they keep baiting you on this is because, deep down, they are not so sure of themselves. They have been told to believe something that goes against logic, reason and science, so they may be lashing out at you because they subconsciously agree with you. I think that is why this debate is so toxic and emotive - it's very hard to maintain cognitive dissonance without it taking a toll on you, and it's becoming harder for even the most committed activists to deny the evidence that people, particularly women, but also children, are being harmed by the consequences of self-ID.
Lastly, I think it's time for you to spend more time pursuing your own interests outside of the family home. Your children need to learn that you are person in your own right, with your own desires and wants, so make sure that if you don't already do this, you start spending more time out of the home doing your own thing, going out with your friends and having fun, instead of facilitating the lives of your husband and children. They are old enough not to need you to do everything for them.
What helped me grow up a lot when I was a teenager was when my mum, who had always been a stay at home mum, suddenly got a job outside of the home and started spending more time with her colleagues (previously she never really socialised much). It was at that moment that I started to see her as a different person and not just as my 'mum'.
