Yes there are probably thousands of religions in existence in the world but it does not logically follow that they all must therefore be wrong.
The logical response to this then must be that none of them therefore must be right, surely?
If somebody wants to follow a particular religion then that's fine. I think the difficulty that some posters have is the evangelism spouted by others. If you choose to believe in a particular deity then that's OK but let's give the pushiness a miss.
For what it's worth, God made the pollution index drop to 34 in Tung Chung today - good on Him (capitalisation only to minimise anger from those who have faith).
As Dave Allen used to say, "May your god go with you".
