About a month ago there was an ethicist on Hack talking about people's right to opinions (about asylum seekers, as it happens, but the argument is general). She agreed with the general principle that everyone has the right to their opinion, and the right to express it if, and only if, those opinions are not based on fallacies - especially fallacies designed to inspire hatred. In other words, no-one actually has the right to spread hate-filled lies. I tend to agree with her.
Yesterday I was accused of being a bigot, on the basis that I show a "stubborn and complete intolerance of any creed, belief, or opinion that differs from [my] own". I'm pretty confident that I tolerate, and indeed respect, a lot of beliefs that I don't agree with, but it's also fair to say that there are some beliefs that I have absolutely no respect for. Those are beliefs that internally inconsistent.
I've argued and debated all sorts of positions. I know that the belief that underpins my world is that there exists an observable universe, and that we are able to observe it. There are inherent assumptions there that people have challenged, but at this stage I'm running with it. I try to keep the rest of my world view consistent beyond that assumption. When I get caught out in an inconsistency, I have to change my views.
I've known a number of people holding various flavours of religious beliefs who have argued with me over the years, and while they start with some differing assumptions, their beliefs have also been internally consistent. I utterly disagree with them, but I respect their integrity.
None of this is the point here, the point is that I really don't respect, or even tolerate, internally inconsistent beliefs. People who claim, for example, that they believe that personhood starts at conception (thereby making abortion murder) but also support the death penalty. People who claim that any religious text is infallible, and then ignore inconvenient bits of it. People who understand how science works, and yet still claim its results are free from subjectivity. And, well, people who believe we were populated by space aliens and that Good People get a planet when they die.
There has to be some measure by which any person's beliefs can be assessed, or we will all have to respect the beliefs of the Sacred Sect of Brownie Worshippers who honour the Almighty Kodak Box Brownie through the sacrifice of chocolate brownies every Wednesday (who have registered as a religion for tax purposes). I doubt that anyone, actually, respects ALL beliefs. There may be other measures besides internal consistency, and if you have some other rule of thumb, let me know. If you think you respect all beliefs, I suspect I either don't believe you, or don't respect your beliefs.
Incidentally, this was sparked by my utter disrespect for Tony Abbott. I have no idea what his beliefs are, since he changes them so often it makes my head spin. A man that can't even own his religious convictions doesn't meet the criteria for respect.
