Remember when liberal meant open minded

Remember when colleges were where you went to get an education and broaden your mind by hearing opposing viewpoints?  As opposed to now, where it looks like a growing number of young people are going to hear their indisputable opinions and beliefs validated and confirmed.  Of course, it could be argued that scholarship has been going that way for a while, as has our media culture in general.  We don't look for facts to challenge our beliefs. We look for facts to conform with what we already know is true.
