I am more keen with converting everyone to liberalism, mainly because I find that regardless of economic beliefs, people who are socially (British-sense) liberal are people I can have sensible conversations with. Committed authoritarians, regardless of political stripe, tend to be much more dogmatic and talking to them is often somewhat akin to trying to break down the gates of Minas Tirith by repeatedly headbutting them. Sure, it may work eventually, but it's just not worth it most of the time.
