How can you have so little compassion? You've never in your life felt regret or loneliness?
Coming to terms with this reality for a woman is even more terrifying than a man because her bodily clock is ticking and pretty soon she will have little opportunity to have a child and dare I say, attract her ideal man. Its a call for more traditional values, to acknowledging that the deal is different for men and women, and its a criticism of responses like this which tell women to embrace being a free spirit when all she wants is stability and steady growth.
Traditional values are truly counter culture in the west, and thats why pol will emphasize it.
EDIT: 4chan also likes it because it serves their tendency toward genetic determinism.
