"It also depends on the ability to change one's mind, before too damage is done."
Actually no you are wrong. Who dictates what is damage and who dictates too much and who dictates their limited view as the right one? In a democracy such dictation is not the way which is why we have democratic votes. Unfortunately damage has been done with over 20 years without a say in being sold to the EU. Now we have changed our mind. After 3 votes to get it!
