Why are right wing morons more likely to comment on sites than left wing morons?

[Torie]

I don't trawl all those sites, but I must say the posts are high quality on right wing Red Racing Horses, but it is focused even more than here, on psephology. Anyway, having stipulated to my relative ignorance, it may be that "right wing morons" are more literate than "left wing morons," so they pound the keyboard more. What percentage of the population is really capable of reading stuff, and typing out posts?  50% perhaps?

And what percentage of the population are intellectually mature and informed on the major issues out there, and can express themselves well?  5%? And particularly these days, many of the issues are extremely complicated to parse. It is not all about same sex marriage, or abortion. It's about Obamacare/medicare/medicaid, macro-economics and tax policy, pension plans, high college tuition costs, global warming cost-benefit analyses and attendant scientific issues that leave me confused (thank heavens for Snowguy there), and a dysfunctional secondary educational system. It's not easy.
