Once upon a time, the money was to provide modest means, for the pastor. Now it is for his mansion, his plane, etc.
Even if this little bit of hyperbole is true, what is it to you? If I CHOOSE to give money to a preacher, even if in your opinion his lifestyle is far too luxurious, it's my money, is it not?
Otoh, what choice do I have when it comes to underwriting the lifestyle of someone like Obama, or any politician?
The issue is less what is done with the money, it's whether the people who provide it are doing so voluntarily. If you choose not to contribute to people like the Preachers of LA then by all means don't. However, just try not "contributing" to Obama & Co.
