Welcome!
You are not a bad person. It's unfortunately a weird world that might have started from a good place (ie being kind to trans people), but which has very badly malfunctioned and misfired. Until you see it, you just see "kind liberals" being persecuted by "horrible old women" (btw I'm 36 and a mother of two, but there is an assumption as to the right "young" position).
You say that you have been on the receiving end of comments about being pregnant and breastfeeding. I'm afraid that this just demonstrates that, whilst being trans might be your happiest self (and will be for some people - those who have very severe dysphoria), it's not the magic wand it is being sold as (and sold extremely dangerously to minors). Ultimately, even if you transition happily, you have to accept the sex you are born on some level, because you can't acquire the fertility or exact same body parts or health profile of a person of the opposite sex. This is just truth.
If you are a trans woman inflating/dilating your neovagina on a daily basis, you have to do maintenance that other women don't - they instead have to suffer periods and smear tests etc. it's not the same, unless you just see a vagina as an orifice for a penis (and even then it's not going to have the same pleasure component as for a biological woman) - ie through the eyes of a man only. Same for a trans man, who needs to pump up their penis to have sex and will most likely have no feeling in it. It's not the same. For some, this is still the best possible option, but it is not the same.
If you look at some older transitioners, the Debbie Haytons, this is a truth that they recognise - they want to live a peaceful life as close as they can be to a woman in form and accepting that they cannot be a woman (which leads them to compromise on other things, access to female spaces etc). This is a path to self acceptance. Unfortunately, there is a subset who want pretence and adulation - this is unhealthy and, when it comes to young people, it is unkind. They are extremely vocal and have captured the permitted narrative.
Giving up on opportunities for young people to be comfortable as their birth sex, whether or not as a gender non conforming version of it, is unkind. Living in one's birth sex is obviously objectively preferable to a life of surgery, side effects and constantly looking through a window at something that you are closer to, yes, but will never have. Some people cannot achieve that and that is fine - they deserve compassion and kindness, but it is unreasonable to expect to live in total denial.
Some of those who want pretence and adulation will also want this for nefarious reasons. Gatekeeping and safeguarding is not hatred.
I wish you the very best, OP. I hope you can build a network outside this - it doesn't have to be a GC network, obviously. Most people don't give it much thought either way (though surveys show that when you drill down they have GC positions on prisons, sports etc). Just a normal one in which you can raise your daughter in her birth sex to be her authentic self with as little baggage as possible.
