I have another conjecture. I think liberals are people who have a very inclusive ingroup, potentially including everybody on Earth; while conservatives have a smaller or better defined ingroup (e.g. Americans). From this follows that there is only one type of liberals, but many types of conservatives (depending on their ingroup). So the view of liberals and conservatives to the others is different, because conservatives tend to perceive liberals as just another group that has them as outgroup, which is confusing to liberals. I think in fact it's similar with religion. Atheism is often understood by religious people as another form of religion, but it isn't in fact, it has a unique position among all the types of religious belief; like liberalism is just an edge case of all possible conservativisms.
