I've been following this thread wih interest.
You've been rather quick to opine as to what is or is not acceptable, yet not nearly so quick to respond to the requests to back up your assertions with scripture, nor to reply to those who do.
To this point, I am left with the distinct impression you are prescribing your personal preferences while criticizing those that don't share them.
You ask, Are you capable of discernment? I would gently suggest applying discernment to differentiate the spirit of David from that of Michal.
“Wherefore we are receiving a kingdom that cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear: For our God is a consuming fire” (Heb. 12:28-29).
With regard to Michal, I'd refer you to the exposition of A.W. Pink:
"And as the ark of the Lord came into the city of David, Michal, Saul’s daughter, looked through a window, and saw king David leaping and dancing before the Lord; and she despised him in her heart" (2 Sam. 6: 16). Saul himself had grievously neglected the public worship of Jehovah, and his daughter appears to have had no sense of the importance and value of heavenly things. It could hardly be expected that a woman who had idols, "teraphim," in her house (1 Sam. 19: 13), cared anything for the holy ark.
