Some people love all of humanity, and support all other humans in their endeavours, especially in faith. For example, in Utah State, in the US, the Mormon Church gave a substantial donation to a Hindu temple there. Myself, I have given money to local small churches where my relatives worship. Without some donations, these local churches may have to be closed. Another example is a lovely Ammadiya Muslim shopkeeper who gives discounts to all things religious regardless of faith. In many countries, governments themselves allow religious institutions, tax deductions for charitable causes.Do you know that statue in Brazil called Christ the Redeemer? It's a statue of a man, his name was Jesus. He walked on this earth long time ago and ate food like regular people. He preached the religion of Ibrahim.
Why would an atheist would support the Christ Redeemer statue?
Tolerant loving people support each other in their peaceful actions, regardless of faith. Only haters and exclusionists don't.
