Here is one very good example. Warning, it is long, and somewhere after about 5 min he throws out a fair amount of profanity. Sixty seconds is really enough to get the point.
Here's one more, from the same 2nd amendment theme.
And one last one of a different nature (Don't wast your time after about 2:00. Very boring and pointless). Yes, I realize I am talking about the constitution and showing a clip form another country. Don't get lost in the minutiae.
The point, imbeciles like this run around "defending our rights" by thumbing their noses, being confrontational, and demanding that our rights be protected. They seem to lack understanding that those rights can be revoked. There is nothing so sacred about the 2nd amendment that it could never be removed.
Instead of investing so much effort in schooling authorities on "The law", their time would be better served in teaching responsible use of said freedoms. Yes you have a right to open carry a firearm. But spend enough time flashing your gun just for the sake of proving your right, and you may very well find that right taken away. And you can then be as belligerent as you want about the loss of freedom, about the Countries descent into fascism, into police state-ism, but it will still be your fault.
