This is an emotional issue and people feel strongly about it, on both sides of the issue. You don't think a conservative Christian wouldn't have the courage of their convictions and do something like this?
Most Conservatives I know are polite, have tact and good manners not to interrupt an official government proceeding in a way that makes Conservatives look bad.
This is something I’d expect from Code Pink or Act Up or Occupy. And would criticize them greatly for.
