Well the 4th level discordants are actually a good thing.
I'm not sure if it would be better to develop treatments for the 3rd levels on down, or to suppress the strains as you say. More than anything right now we need social awareness of the phenomena. Socionics is the tool of choice for putting their hangups in context.
Additionally, note that I didn't distinguish between social and antisocial discordants. These are general traits of all of them.
