Having respect for something is not the same as tip-toeing around it. You can say everything you wish/believe only edit jibes/taunts/mockery/insults. Your point in turn will have more credibility.
What jibes? If you look up the dictionary definition of the term "mumbo jumbo" you will see that it could not possibly be construed as offensive.
From Webster's online dictionary
1 : an object of superstitious homage and fear
2 a : a complicated often ritualistic observance with elaborate trappings b : complicated activity or language usually intended to obscure and confuse
3 : unnecessarily involved and incomprehensible language[SIZE=-1][/SIZE]
4 : language, behavior, or beliefs based on superstition
Why do followers of a religious doctrine feel they should be automatically afforded respect not shown to any other scientifically groundless ideologies such as the belief in fairies, elves, guardian angels, astrology, palmisty, homeopathy and so forth?
