Has America Become Content With Superficial Christianity?

I'm not a big fan of excessive complaining, and I even consider myself an optimist.  But certain things about the expression of Christianity in America worry me, especially when I start to see them in myself:

Instead of trusting in the Lord, even with our money, we are content with putting “In God We Trust” on our money.

Rather than honoring Christ the Lord as holy in our hearts, we are content with honoring Him on our t-shirts and facebook profiles.

Jesus said to take up your cross and follow Him, but we are content with taking crosses and putting them up on our walls, and following Christian blogs, podcasts, and "tweets."

We were told to be diligent to make our calling and election sure, but we are content with being diligent in electing politicians who are Christians for sure.

When we should be asking if the Lord’s laws are written on people’s hearts and on their minds, we are content with having them written on courthouse monuments and in our nation’s statutes.

Are we becoming content with superficial Christianity?
