The only reason to get kids is to pass on half of your genes.
Most people shouldn't be passing on any fraction of their genes.
Thus, most people shouldn't get kids.
If you're one of the lucky few who actually reproduced for a different reason than A) "ZOMG instincts taking over", B) "Oops" or C) "Kids are sooooo kute and wuvvable", congratulations on ensuring the future survival of some of your genes for another generation.
Just don't mess up the parenting. Nature only accounts for a part of the personality, the other part is nurture.
Otherwise, fuck you for cluttering up our gene pool.
