headinhands, you've misunderstood and incompletely quoted my previous post to alter its meaning (from respecting people to respecting beliefs). You should've quoted that line in full:
The most serious concern for me is the lack of respect and care shown for others as real human beings
And thus in replying with: "Beliefs don't need respecting. The idea that we should automatically respect them is both dangerous and silly", you are mistakenly answering something I never said and a point I didn't make 
.
Of course some beliefs are very dangerous and lead to hatred towards others, such as the example you gave, and thus your statement about not automatically respecting every view is valid, and measures should be in place to address and curb those, and indeed there are such things (eg. anti-racism and hatred laws, etc.). If expressed in the context of an online forum like this, I would expect such views to be deleted by the moderator and the poster possibly denied future access.
But as I say, all that's completely missed the point I and others have been saying. Which is, that it IS fine to express disbelief and different views, but HOW you do it is very important and personal attacks on someone (others have given examples of this) are NOT acceptable.
Hope that makes it clearer. But if not, consider this: If your boss or good colleague at work made a suggestion on how something should be done that you thought utterly ridiculous, how would you answer? Presumably you would rightly say you didn't think it was a good idea and explain why....but would you also make personally attacking statements about him/her (eg. telling them that they're stupid, an idiot, etc. for thinking and suggesting it)? I would hope not.
But hopefully you get the point and appreciate the distinction
