After a long debate in real life regarding this issue, I have decided to change my stance on the issue. I no longer believe that any man (or woman) has a right to not be responsible for an already born child (I am still pro-choice). No more child support, but men have to take care of their kids every other week (assuming that there is nothing wrong with them or they are not criminals).
It's a child, not a wallet.
NOTE: Changing my views does not mean I flip flop, it means I actually think for myself... times and times against.
