For the most part, the areas in which we expect others to be consistent are those areas in which we have no trouble with being consistent. If certain sins are no problem for us, we cannot understand how in the world they could be a problem for anyone else. Of course, the sins with which we struggle are sins which require the utmost patience and understanding from our brothers and sisters (either that, or we take the easy way out by simply hiding our sins and praying that no one ever finds them out).
