I also usually do this to know who I'm talking to and how I should talk to that person. As much as I have labeled it, it is the easiest way to define a huge group of people who have common ideas. In my daily life I am very political and I rarely get into discussions, I express my thoughts, which I consider to be libertarian, in a healthy way and when I am provoked to do so. I'm still learning this philosophy, but for me it's the one that best represents the world and human beings.
