Care to elaborate, because I am not following your argument. The fact is that many of the founding fathers were extremely critical of organized religion, from Jefferson to Adams to Franklin and many more. The separation of Church and State (a phrase which Jefferson coined) was meant to stop goverment from sanctioning a particular religion. I am sure they meant at the time any Christian demonination, but it is nice how it neatly applies to all religions in general. Having the goverment say marriage means what the Christians want it to mean goes against everything this country was founded on like tolerance and freedom, and is wrong. Simple as that.
