"...they refuse to....become responsible..."
I reject the implication that their lack of responsibility automatically becomes the responsibility of responsible people by force of other irresponsible people.
If thugs attempt to force your behavior on me I will blow both your gd heads off.
In re the Overpopulation Panic:
It has been reliably established that the entire population of the Earth could be comfortably ensconced in the state of Texas - resulting in a lesser population density than that of Manhattan.
But then who'd want to live in Manhattan.
Just because a fact such as retarded cultures exist does not mean that this fact is a problem to be solved or that it even can be solved, ...it just is.
It's a fact. Not all facts are sunshine and lollipops, or solvable problems just because some of us have a vision of what we think is "better".
