Aside from the "sympathy with the devil who sympathizes with me," I'm amused (or horrified depending on the day) that conservatives are incapable of understanding that there are also left wingers who have political and societal concerns and their basic reasoning should apply equally to them. But, of course, they don't because liberal concerns are completely invalid.
The point is that if some liberal started shooting up catholic priests, or whoever, pissed off because of abortion laws, I doubt Chunky BoBo would write a "extremists only grow stronger when a political system pretends that problems don’t exist" column. It would, instead, simply be a lesson on the evils of liberals and liberalism and blahblahblah.
