Actually Vanni your sincerety is honorable, so no problem there.
In fact I find most of your views most accurate on this subject. I personally wish that all the churches review their historical origins but I think the outcome would be different than you propose.
I think a realistic honest look would deepen the religion, make it more mature and wise. I do not think an honest look would destroy the faith, the religion or its attendant institutions.
No doubt most would fight it, not allow it, take great offense by it, because they would be fighting so hard the bad qualities of their attackers.
Also, the general quality of the church goers have become a subject to be ostracized or ridiculed by the secular humanists and so I am just trying to get some middle balance there.
My instincts tell me that the religious radicals and secular radicals, the atheists with an attitude, the political types who hold logic and facts as their only God live all in the same glass house, and they are all basically all the same, and who I believe to be the least mature of the species.
