This is because, actually practicing the Christian faith vs simply performing theatrics are different things.
From my own experience of someone who practices regularly, there is a minority of people who really follow it. They show up to the daily Mass, perform Works of Mercy, do charitable work, etc. The truth is that Christianity demands _a lot_ from you, including saying no to greed, lust and gluttony.
How many people are willing to say no to an extra 200k so that someone less fortunate might benefit? Or open their homes to strangers, so that they may not freeze in the cold?
I think that one of the worst thing that has happened to our faith is its hijacking by the government for political gain (some lower Churches like Evangelicals are currently _heavily_ suffering due to this).
I'm a Catholic but when I speak to my Protestant friends, they feel the same about their communities. Luckily, we still have each other and Christ to help guide us.
