Here is Nick Cohen's take on people asking for their religious beliefs to be 'respected' and not laughed at or argued with. In my opinion, he has it exactly right.
Politics is as much a part of the identity of the committed leftist, green or conservative as religion is of the committed Christian, Jew, Muslim or Hindu. When the political partisan's beliefs are insulted or ridiculed, he feels the 'offence' as deeply as any believer who has heard his god or prophet questioned. We do not, however, prohibit or restrict arguments about politics out of 'respect' for political ideologies, because we are a free society. We call societies that prohibit political arguments 'dictatorships', and know without needing to be told that the prohibiting is done to protect the ruling elite. If political or religious believers are offended to the core of their being by criticism, free countries must reply, 'Tough. Learn to live with it. We know that we tell white lies about many things. We accept that the truth can be suppressed on some occasions. But religion and politics are too important and too dangerous to risk handling with kid gloves.'
