You might feel differently if your kid had been raped, say. When you only have one principle to deal with, life is simple, but I think there are grey areas in all these issues.

Similarly, the argument to legalise drugs. Personally, I agree with the argument, but a similar demand-supply problem exists in human trafficking (e.g. child sex slavery), but there I think the laws should continue to keep the latter illegal even while it supports the high profits that human traffickers can make. What do you think?
