I think that at this point in my life I have quite a lot to show for. I feel quite successful, particularly when I consider how since my own birth seems like I was set to fail. Hence, I don't think that I have to have or give any reason for me to succeed without religion. My life so far is my reason.
That said, in now way am I trying to make what others share invalid.
The attitude of some churches toward tithing really is a problem.
Some churches are all about money. I've even known of some churches where people have to apply for membership and they have to be approved, and part of the application involves showing proof of income. I know that running a church and some of the community services that some churches run cost money, but time and time again the amount o money that they receive many times surpasses what they need for those programs, not to mention that many times they obtain funding from grants and foundations.
