1. It's not enough for you to yell at your kids if they made fun of other kids. If you want to change the world, it's incumbent on you to make them sheep dogs: to step up and prevent others from doing it, even at the cost of getting beat up themselves. We've all seen the spate of school beatings recently when no one steps up to do anything to protect the victim (whether for physical fear to themselves, apathy, or in some cases fear of being labelled racist). Want utopia? Encourage your kids to be sheep dogs not just stopping them from being sheep. They have to stand against the night against the wolves, even at the cost of their own safety.2 & 3 - It appears you're pretty much saying the same thing in both, which is: The mistakes of the past and jerks in society will ruin it for us because they will still continue to berate MTF. No doubt there will be people like this going forward, regardless of what "solutions" are put in place. There will always be people who behave this way. However, it doesn't mean the majority will behave this way. Look how far we've come with so many things such as gay rights. Listen to the people on this forum, most of us DO NO CARE IF SOMEONE DECIDES TO WEAR A BOW OR A CAP ON THEIR HEAD. We would also yell at our kids if they made fun of other kids for doing so. Yes, our generation defined gender roles too much but we've really come a long way as we see a lot of dads as the better home parent and lots of moms as the better career person. We've also see both genders share home responsibilities and financial responsibilities. We've come to realize previous gender roles are too narrow and are really just UNNECESSARY. We do not need definitions of how each gender should behave or accessorize themselves.
Continue to address and focus on the real issue - which is - let people be their individual selves. I absolutely believe and have seen that our society is capable of this.
2. I really appreciate your vision. It's a very thoughtful and compassionate way at looking at the world.
3. I think you overlook, though, that for the trans kid that is transitioning, they may face all this, but at least can be comfortable playing in the gender to which they prefer. "Well, everyone is going to make fun of me, but at least I can be who I am". At the youth level we don't care about the fair playing field. I'm not saying they should be forced to transition to play with the opposite gender....they should have a choice of what makes them the most comfortable, given there is, on the youth level, no counterbalancing factor you can articulate to prevent this. It may be your utopia, but it's not necessarily there's.
4. One thing I agree with Jordan Peterson is that gender is not a construct. I think you are just wrong about that. Men and women are fundamentally different. The brains of trans individuals also seem to support this: they are literally the different brain stuck in the wrong body. This is something akin to a disability, not a way of being. It should be treated as such.
