Most Exercised US Right
We have the right to succeed. We have the right to fail and even fall flat on our faces. We have the right to vote. We have the right to screw up that vote. We have so many rights all based on our freedom.
The most exercised right I would say is the right to be stupid. How often to people make stupid decisions. When I was in college that was obviously the most practiced right.
When it comes to fixing something we did wrong because we exercised that right well, that is a privilege. We have the right to be stupid, but fixing the mistakes we made in exercising that right is not a right itself. I have the right to tell someone off, they give me the privilege of hearing my apology. Not everything is a right. But, the most practiced right is being stupid. But, correcting the repercussions of that right most of the time is a privilege.
