You do know they were not in trouble because they were protesting but how they were protesting.Unless you are driving a truck to Ottawa
Let me explain this to you via protest which you seem a huge fan of.
Tell me where you live, I'll show up at your home, blaring my horn at all hours in the morning and block your ability to enter and leave your home as well as harass you. That would be fine right, because protest.
I suppose if I want to protest something by smashing a baseball bat across your skull, shitting on your yard and fucking your dog, hey, freedom of speech right.
Fuck, it's been ages, people must have pointed this out on some thread you have read. What is it you don't understand.
[and I feel the same way about any protest where people get in your face] Your right to free speech ends at my face, much like your right to fuck, to religion, to association etc. ]
Funny how people who fly the banner of freedom seem to have no problem forcing themselves on others.
