The whole problem is that instead of those who struggle with this problem asking for help, they turn it into a lifestyle.
It is like reform that made a movement out of breaking halacha – or clans of tzigane in this part of the world who have been making a living from stealing and begging for generations now and claiming it is their ancestral way of life.
Those dealing with this toeva should be storming Congress the way yenna machla patients, genetic disease sufferers, spinal cord injury victims LA etc are doing to ask for research and a cure for their disorder. They should not be legitimizing this any more than a kleptomaniac or a pyromaniac should claim that his disorder is an alternative lifestyle.
As for the marriages, the only ones who benefit will be the divorce lawyers. People with this toeva are very volatile and rarely maintain relationships over a long period of time (yes, there are exceptions).
