I grew up with right wingers controlling speech a lot like the left controls it now. Neither side cares about free speech, but they only complain with the restrictions affect them personally. Right wingers sound libertarian now only because they are the most restricted at the moment. But, like you said, they want to control speech too. Not sure if I agree with all of your examples, but it's a fact that they do the same stuff to a lesser degree.

Left wingers were the more libertarian group when I growing up. Which is why I just stick to libertarian ideology and don't try to align with the left/right stuff.
