We’re losing the intellectual battle because we never even present our ideas - those upon which our country and all of Western civilization were founded. We have been undermined by the left and our own professors and even secondary school (and probably primary, too) teachers, who hate the US and reject our foundational thought. We’ve got to go back to it, revive it, and teach it if we want to survive.
And we need to practice what we preach.
Rampant and unadressed corruption within our own government undermines the message of virtue inherent in the principles which underlie the founding of this nation, and the current practice of undermining our own Constitution for electoral and other expediency makes us hypocrites in the eyes of the world.
If we cannot live within our own Constitutional guidelines, and keep our government within them as well, there is no way we can credibly preach that way of life to the world.
