You really don't see how ridiculous an analogy this is?
I mean, the premise doesn't even make sense.
That you have to resort to using such a ridiculous analogy is all anyone needs to see to recognize that you don't have a good point to make.
Anyway, if I raised the child and came to see him as my own, yeah, I would feel responsible for him, same as any other adopted child, so... yeah.
Why am I responsible for adopting the children of criminals who enter the united states illegally?
Society as a whole has voted that no, we are not responsible for that. We have already decided that we are not responsible through democracy. You are actively trying to undermine the law. If you want change then you need to cast your vote and walk away. The law is not going to change through your tears.
Because the US has never adopted immigrant-friendly laws before? Actually if you stretch your analogy further, you shouldn't be responsible for anybody else, whether illegal immigrants, their children, or natural-born Americans. But you are, aren't you? I mean, you're a Republican, so I'm sure you don't agree with it, but you're paying for poor people on welfare, you're paying for public schools for your community, you're paying for medical care for the elderly... despite living in a democracy!! Maybe one doesn't really have to do with the other?
If the law is going to change (and I agree it should be done properly, which is why I don't count this as among the worst things Trump has done), it will be done legally through Congress. And the Dreamers have enough support on both sides of the aisle that the law changing is a distinct possibility. So sorry about your luck, I guess. Our democratically elected leaders might just be more compassionate than you.
