""Why single out Christianity?""
Pay attention, Keith.:)

Actually, that has not been the case, if you actually read posts, (it has already been suggested you dont read attachments, even when they refer to a question you ask) you will see references to organized religions. Christianity is a major one, worldwide, having a major impact over the past thousand years, it can be expected to be very influential.

Because the OP and the discussion was primarily around the USA and western counrties, where Christianity followed colonization (influencing governments and cultures), Christianity has been a central factor. (You may wish to reread the OP to freshen up).

No person has said that there were not other influences on bans on gay martiage in the west or in other global locations, Keith- you were the only one who refered to that silly notion.

Welcome back GFS, I suspected the topic would bring back the old team.
