Well you don't have short term capital losses if you don't sell in less than a year. And, if you do sell at a loss after a year passes then you have long term capital losses. Both types of losses have their relative values tax-wise.
An important point however is that sometimes when you choose to not realize short-term capital losses it gives you more time to later possibly realize long-term capital gains. But, I would gather from you comments that you are not really interested in, and know little about, the advantages of long-term capital gains.
