Birth Rights

Today, I am taking issue with the often-assumed 'right' to have kids. I'll go into detail for any of the issues if requested, but here is a quick summary as to why we should have very limited rights when it comes to having kids.

1: Over population.
Ahh, this one is most likely the bane of modern society, yet no one ever talks about it. It will doom us, we simply lack the backbone to talk about this. C'est la vie eh? Too many people are having too many kids, the Earth and its ecosystems simply cannot handle it. I'm of the opinion we already past our carrying capacity (with a high lag time). Look at animals/plants. Amphibians are down to 2% TWO PERCENT of their populations only years ago. This is not natural, humans are the cause. When joe has 10 kids, and all ten of them have 10 more, he just raised his problem 100 times, and he was probably worthless anyway.

2. Mental 'Illness'
Why on Earth should someone who is 'mentally ill' be able to have children? Let me state up front that I believe first that a large percentage of these cases are fakes anyway. But sifting that useless rabble to the side, we are left with the people who have brains wired differently, unbalanced chemicals etc. This next line will be considered cold,crash, 'racist' (most people have no idea when they use this word) :
Why do we even tolerate these people, and esp. give them the 'right' to have kids? If you gun someone down, and are 'insane' Fine. *BOOM* -dead, 'next criminal will you please take the stand?'

What kind of defense is being 'insane'? It should not be one, and if you are convicted of it, you should just be eliminated, much to society's benefit. For Earth's sake, do not let them have more kids!
