You’re comparing apples to oranges. King was talking about moderates who were vacillating over supporting civil rights out of fear of tension, not kids in the foster care system. I’m 100% for updating the Civil Rights Act to say you can’t discriminate against trans people, period, and automatically invalidating all the insane laws out here.
What we’re talking about is pulling kids out of homes. And the evidence on that is clear: Bad homes are better than foster care. I’m sorry that your childhood sucked, but statistically speaking, your life statistically would not have been any better if you had left home, and may have actually been worse. Yes, it should obviously still be an option in extreme situations, but your proposal that such a thing should be implemented when the evidence shows that it will cause more harm is not a viable solution to the problem. All it will do is put more stress on an already broken system.
Sure, magically if we could make the foster system perfect tomorrow, and magically could fix all the laws tomorrow, then maybe it would make sense. But if we had that sort of magic, we could magically fix shitty parents, too.
