I go both ways here, for adoption.
For it: I'm for adoption but only if it's is for the absolute good of the child, such as being a very unfit parent, or too broke or something to take care of the child
Against it: I'm against it if you're just a teenager who happened to get knocked up, suck it up, you should have used protection or something, if you just don't want the kid because if wasn't in your plans to have a child once again, suck it up
I don't like the fact that there are children who are put up for adoption and maybe will or probably won't be adopted.
If the child's adopted and doesn't know it, well, their likely to find out later in life, and hate you or want to get to know their birth parents or something
If the child's not adopted then what are the chances that the child is going to have to go from foster home to foster home for a good chunk of their childhood wondering if there is anybody in the world that would really care about them. And what if the do find someone to love them but can't be adopted or something by the person and get taken away, the child is likely to hate everybody.
