We as Christians have no "leaders" other than Christ. These people may claim to be "leaders" of other Christians but they only speak for themselves, as in the eyes of Christ, they have no greater standing than anyone else.
With that being said, these people have no business telling us that we cannot exercise our God-given rights to ask these questions of our leaders. Perhaps if they wish to promote the facade that they are actually Christians, as opposed to heretics impersonating Christians, then they will respectfully STFU as we Christians choose to exercise our rights.
Excellent point.
