Why, then, should we be commanded to “respect” those who insist that they alone know something that is both unknowable and unfalsifiable?
The article asks this question, which is fine to ask. I think it hinges on what is meant by "respect". I am free to disrespect a religion, or not, on my own. I'm generally free to make that notion known broadly, in the US, but it avails me little or nothing or even negative reactions. I don't "respect" Islam, I try and understand a bit about it in its various incantations. I'm not going to "disrespect" an individual Muslim with it. It seems ... disrespectful of another human being.
I'm obviously not a Muslim. I do think evidence shows the vast majority of Muslims are peaceful folks. Some are obviously not.
