How Dawkins made me a better person

I mean every person that the athiest movement convinces to leave religion, makes one less person donating their time and money towards the charitable initiatives of the church, = less for charity.

Lets assume that all the people who leave the church commit the same donations to secular charities instead(unlikely, but a percentage probably would), what about the lost volunteers?

In fact there are many secular charities exposed as fraudulent regularly or with rediculous operating costs, some as much as 95% used up on admin expenses. Secular charities are regularly exposed as being wasteful. I watched one documentary which exposed Unicef in Vietnam, charity staff living in resort style luxury and multi million dollar car fleets sitting idle while homeless single mothers where found begging on the same street.
