Why can they not simply ask that churches invite Muslim and Jewish clerics AFTER services and have them talk about their faith? Why do they need to be in the SANCTUARY? If you really do believe your religion is true (and Judaism inherently denies Jesus even as a Prophet, Islam denies him as God but calls him a Prophet, and Christianity accepts him as God, therefore on that point alone they are prevented from all being equally true), then why would you invite another religion's clergy into your sanctified place?
Most of them don't even have the conception of anything
being holy at all any more. Or true, for that matter, which is the root behind this all. Our society nearly worships uncritical equality, regarding everything as equal regardless of whether it is true or not, so people believe everything has to be given "equal time" in all milieus and other ridiculous things.
I'm meeting a increasingly number of people who think to hold concrete beliefs, ex. that something is true, is biased
. The World is bullying people into making no distinction between wheat and chaff... And this is really another example of that.
