Being a liberal is the default state of someone who lives in this world, because of the education system, the media and social networks. It doesn't mean that they are SJWs or communists(well not all of them), but that they only watch mainstream news channels and John Oliver's show. It is also possible for them to be converted, but it has to be done incrementally, and you can even start on good legging if you say that you dislike Donald Trump, but not for the reasons they do.
Don't go sperging out saying that we need to disolve government and other things equally dramatic, but start with things like, "Do you think it's ok to tax people who are pro life, to fund abortion centers like Planed Parenthood?" or "Let's say you have a good cause to which if you donate, humanity will overall be better. Are you justified to use force or the threat of it, in order to persuade others to donate? If they answer no, then ask them if politicians should and why." or give them the tale of the slave http://www.colorado.edu/studentgroups/libertarians/issues/nozick_slave.html
