Not at all, you are free to piss off, ridicule and lampoon government (which is, lets face it, most peoples 'God') all you like. You can even vote for a new one, not that that's ever likely to happen. But like all fragile religions there are lines that you don't cross, and if you do you can expect the full power of the inquisition to fall on your head. Snowden, under the delusion that we are a free people living in a democracy and that the constitution and bill of rights still apply (silly boy) thought that the Holy Government was doing things that the people it's laughingly meant to represent should know about. And now he knows better.
You can draw funny pictures about government and politicians all you like.
You can't draw the Big Mo with a funny hat without risking you life.
