but teaching homosexuality is normal and homosexuals should marry is ok?
This is the same William?
I don't think dear William is a follower of Christs' teachings.
He stands for NOTHING so falls for ANYTHING:
Rom.12:2
[2] And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
He has decided the world knows it better than God.
Even he, is without excuse:
Rom.1:20
[20] For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
He has faith in man; NOT God. The poor soul doesn't realize that SCIENCE supports Creation too!
