Perhaps you have knowledge of ones that I don't.  What I've heard from friends, family and others is that most CC, Tech and Trade schools are aligned with market needs for skilled workers.  Hard to imagine how HVAC or Carpentry classes could be tainted with liberal ideology.  Conversely, there are many examples in places like Japan where companies do teach the needed skills for lifelong employment.  But, could you imagine the training that could come from places like Google, Facebook, etc?  Those are suspect already with their censoring of Conservative thought.
