Remember grade school, when the most demanding question put to you was something as simple as "What color do you like?" Choose any color, for there is no wrong answer.
This is the power of "like," where nobody can dispute your preference. You don't have to give a reason why you like something. You just do.
In adult society, however, things are more complicated. When talking about, say, governments, societies or complicated social situations, a simple answer of "I like it" without a reason won't do.
