{I sincerely hope that I did not completely change the intended meaning of this sentence by omitting several words:}

Simply using abortion as a means of ridding oneself of an inconvenience....as in simply being too lazy, stupid or drunk to ensure adequate contraception methods are used, is morally repugnant, irresponsible and a sure sign of society in decline.

So, a woman gets drunk (or her date gets her drunk), has sex while in a state of diminished capacity (or maybe she is entirely unconscious), and becomes pregnant. Newsflash: this is what is called rape.
