There is faith and then there is Fraud. Let's not confuse the two.
Jesus came to the rich and said "sell your possessions and give to the poor..." Joel Olsteen and his ilk come to the poor and say "sell your possessions and give the money to me".
You are right that there is a big difference between being anti-Joel and anti-Christ...
I have respect for the teachings of the Biblical Jesus and anyone who truly follows them. A lot of people who claim to be Christian don't even make the attempt to follow Jesus.
Joel Olsteen, with his $40 million mansion and his message of greed and intolerance is the opposite of the biblical Jesus.
