One thing, all of you who may have an IQ that is WAY above average, who then look at Overpopulation and then think 'This makes me not want to have kids'.. you are like the couple in the introduction to Idiocracy.
If you've seen, then you can recall that they put it off and off and off, whilst the dumb fuckers keep on fucking, regardless of your ethics on overpopulation or how bad the economy is, oh the world's going to end this, that and the other.
This is WAR for survival, civilisation will end, so what, masses will bleed rivers, that doesn't mean the elite stop passing their genes!
You remove the weaker/ lesser/ stupid/ undesirable and take the captured resources for your own genes to have a hope in hell's chance of surviving into future centuries.
Overpopulation is a problem, sure, but the cause does not lie in our own low fecundity elite (I mean that in an actual mental and physical way, not simply economic) it lies in the impoverished masses and the false-moneyed elite (who are mostly economic, who encourage dysfunctional consumerism above the health of a civilisation) who are out of control and YOU must not take guilt-baggage or your lineage (that could potentially rear great leaders, scientists, whatever your potential - in future generations) is as good as dead, if there isn't enough space, CLEAR SOME.
