To liberals, being "open-minded" also means that one "does not judge." To liberals, casting judgement on something or someone is avoided because the act implies a level of goodness, a standard of excellence. Liberals abhor having to live up to standards.
Liberals are always open-minded when it comes to other schools of though, ways of life, and cultures. Ironically, they are close-minded to anything western, Christian, and particularly American.
"Don't judge that long-term unemployed person, because you don't know what they've been through!"
"Don't bad-mouth that culture...they have some of the most sustainable and green lifestyles!"
You’re right - they hate standards that they don’t define for themselves. It has to do with the need for righteousness that God created in us. They don’t want to live to His standards (and we know that’s impossible anyway), and only want to live to their own, self-defined standards.

“To liberals, being “open-minded” also means that one “does not judge.””
I’d say it’s more accurate to say they don’t want people to judge for themselves. Liberals have no problem pronouncing judgement on things, but only like to condemn those things that all liberals have collectively agreed to condemn, such as racism, birthers, Christian “fundamentalists”, etc.
As you say, they appeal to moral relativism to say we shouldn’t judge other cultures, but they have collectively pronounced judgement on Western culture, so they feel free to condemn that.
