Someone who really cares about you will tell you the truth, even if it hurts.
Alright then, here's some truth.
There are three stages to losing your sense of patriotism.
1) When you realise the present, is not what you believed it to be. (ie America is not #1 in everything, tortures people, has faults, whatever.)
You are at stage 1, as are most political activists. (i.e. we have been a great nation, and can be again)
2) When you realise the past, is not what you believed it to be. (The abuses against other countries or the American people, are not a new thing. History is full of examples, but most people don't know their own history.)
3) When you realise the future, will not be what you believed it to be. (Repressive laws don't get rolled back. Authority does not relinquish power.)
