You're kind of getting to the root of an important problem with this thread, in that I think we need to define exactly what David Silverman meant by "respect" in this quote. Personally, I interpreted it as a kind of reverence - i.e: treating religion with respect basically means not questioning its tenets or criticising it, or giving it undue prominence. However, many in this thread seem to have interpreted respect in a more general, colloquial meaning - i.e: the respect for people's rights and for individual freedoms. Unfortunately, the source doesn't really give much context as to what David Silverman really meant, but I think if we can make the distinction between respect as an act of reverence and respect as an act of tolerance, we could probably move forward in this debate a lot quicker. I summed up my position earlier, but I'll just clarify by using this new dichotomy.
I do not believe that religion deserves respect as an act of reverence by default, as no ideas should be revered in and of themselves and should stand entirely on their merits with regards to individual benefits and truth value. The fact that religion is held so closely to the hearts of so many people in such a personal way makes it all the more necessary for us to question, criticise and, yes, even mock religious ideals when we feel it is warranted and justified.
However, I also believe that religion deserves respect as an act of tolerance just as well as any other ideological system does. People should have the right to believe what they wish without persecution on consequence, provided they live in accordance with the rights of others. Religious individuals should have the freedom to practice their beliefs without fear, and nobody should have the right to force their beliefs upon others or have their particular beliefs given precedence in law. All human beings, regardless of beliefs, are entitled to free speech, freedom of religion and freedom from persecution, political or otherwise.
