Here's the actual definition of liberal, for anyone concerned.
lib·er·al ˈlib(ə)rəl adjective
1. open to new behavior or opinions and willing to discard traditional values. "they have more liberal views toward marriage and divorce than some people"
2. (of education) concerned mainly with broadening a person's general knowledge and experience, rather than with technical or professional training. synonyms: wide-ranging, broad-based, general
"a liberal education"
I think Liberals are stuck on broadening a person's general knowledge because I do not see any progress on that front. In fact I see quite the opposite. They are behaving like cave men. You know chasing women out of restaurants, uttering threats to 12 year olds and so on.
