There is no need to respect that belief, particularly a great deal. Just because you hold an opinion does not mean it demands respect. Not all ideas are equal. I have no respect for barbarous dogma and the related mythology.
I have respect for people with deeply held beliefs, religious or otherwise. I may or may not share those beliefs, but at least you know where they stand. It's quite uncommon in our age of moral relativism. It's the desire to forcibly impose those beliefs on others that I do not much care for.
