I am often told I should - and I have been told that I haven't. But I genuinely don't know what it means.
I am a great believer in good manners, and I would always be polite if I was attending some sort of faith based event. I never go on prayer threads. I do try never to be rude. But the threshold for "disrespect" seems extraordinarily low- sometimes mere disagreement seems unacceptable.
Also, what constitutes a "belief"? The major world religions- OK- I get that. But do I also have to respect "new" religions made up in the 1970s/80s? Kabbalah? Is homeopathy a belief? If I say, for example "homeopathy is discredited bollocks and this is why" is that a public service or disrespecting someone's beliefs? Is astrology a "belief"?
Atheism isn't a belief system, obviously, but am I entitled to be offended and report the post if someone says that atheists lead empty lives devoid of joy? Or if someone says that science is evil and devoted to hiding the evidence for the paranormal/ the cure for cancer/whatever for it's own selfish ends?
