Whining and bitching is the most American thing you can do. It often means that you see something that can be improved, and democracy is supposed to be about eternal vigilance.

Being proud of your country should mean being proud not of our current laws, but of the constitution that allows us to fix those laws when they are deficient.

If the government still recognizes the authority of the constitution, then you can fix the constitution via amendments.

Otherwise, it would be time for a new constitution. But of course, in that case, there would truly be nothing to be proud of. It would mean your entire country and government was a complete failure, and that whatever new constitution you ratified would have to make many provisions to protect the government from the overwhelming stupidity of the citizens.
