I am probably being a little intolerant. But no more so than anybody is when faced with things for which people refuse to provide objective evidence.
Richard Dawkins is always accused of intolerance. He's had it up to here with people who refuse to argue properly with him, though, so I hardly blame him. My brain is also small compared to his and so is lilely to explode with frustration more quickly.
If I am a Labour voter, Is it "disrespectful" to ask the Conservative candidate to provide good, solid reasons why their way is better, rather than just accepting "it is"? If I prefer Doctor Who to Star Trek, I expect that a Trekkie will provifde decent reasons why their programme is better acted, scripted, directed, etc, than mine. (They'd still be wrong, but they would at least have argued it with evidence!)
It's a bit like being told over and over again "the moon is made of green cheese", and everty time you say "but, it isn't, and NASA has these pieces of moon rock which prove it", you're told "ahhh, but I BELIEVE it is and I have personal expereince of lunar cheesiness which you can NEVER know fully, so I am right and you are wrong."
