Do you want a child born into slavery?
Do you want a child subject to a totalitarian government?
Do you want a child born into extreme poverty or famine?
I feel like if you want to have a kid you have one and you deal with whatever adversity comes along.
Take the opportunity to prepare your child to deal with the world that exists regardless of the circumstances. The more children that grow up with thoughtful parents that prepare them to face problems in the more possibility the world will be a better place in the future.
I'm sure my argument isn't well thought at being that it's 4:30pm on a Friday, but I really feel like regardless of the issues we face in society today we are living in the best time to be alive ever and if you have the means to care for a child, and you want children, there's nothing that should stop you from having one.
