Back in history everyone was bad by our standards.
You should not rubbish a modern institution because long dead predecessors did things unacceptable today.
Christians aspire to be loving, tolerant, and forgiving. How can that be bad?
There are some wacky churches, but the ones I know, Anglican and Methodist, could not be faulted in their giving.

In most charities and even the environmental movement you will find that people of faith are present in disproportionate numbers. Thank God for them.
