>But why are conservatives so good at it? Lot's of practice?

The conservative movement is more closely related to a single ideology (memeplex) than other political beliefs.

These memes are highly skilled at replicating, which means they are very good at controlling their infested host.

Once you've read the essay, the definition of memebot is most relevant here:

membot: A person whose entire life has become subordinated to the propagation of a meme, robotically and at any opportunity. (Such as some Jehovah's Witnesses, Krishnas, and Scientologists.) Due to internal competition, the most vocal and extreme membots tend to rise to top of their sociotype’s hierarchy. A self-destructive membot is a memeoid. (GMG)
