Surprisingly not offensive.  On the flipside, ignorance is part neutral.  Obama-ites had the exact same reactions at his signings.

They have valid points, social responsibility, government distancing, etc… but have absolutely no idea of scope and application.  It would take years to explain the core problems in the US to the majority of Americans, which is sad.  Though from a good side you can clearly see that the people standing in line are not in any way shape or form the same age group of people that follow Obama.  I really wonder where the Republican youth movement stands.
