That is just another belief people wish to impose on others. It will always fail while there is a genuine freedom of belief because beliefs can be mutually incompatible (X believes Y which compels them to hate W because W believes Z). I'm not even sure what people really mean by "respect" in that context. If I believe in a sceptical, evidence based approach to life, how can I meaningfully "respect" someone who believes in something that I believe is "woo". And someone might show the ultimate respect of my beliefs by challenging them. Whereas if I challenge the religious beliefs of someone in exactly the same way, people might tell me I am "disrespecting" them. Respect is relative and in the context, probably largely meaningless.
<ideal world> It would be nice if people could have their various religious or non-religious views/beliefs and be able to respect each others difference of opinions.</ideal world>
