Well, Gmail has a good learning algorithm :) I definitely agree with you that these points are argued but I don't believe, or perhaps hope, that they represent the majority of conservatives.
I think it's considered fact that right media is significantly more sensationalist. Naturally, this turns "I humbly disagree" points of view into "You should hate because" arguments. In the same sense that they don't report on the moderate right, they also don't report on the moderate left. It could just as easily be said that I heard "in a liberal America, everyone will drive a Prius" in a chain email. Of course you wouldn't hesitate in believing that is false.
It's not that Fox News doesn't actually report the news (despite a perpetual joke deeming otherwise) it's just that it skews points to make them more approachable for socially conservative voter. They must say that "abortion is murder" to their party because it consists of people vehemently against murder and more importantly, people against redefining their definition of murder. Conservatism itself is defined by this a lack of progressivism and without it, most of the social stances are blurred if not completely flip flopped.
As you know, most voters aren't that informed. Nearly nobody, left or right, ponders real solutions to the problems facing the government. Instead they have a belief, usually predetermined, and look for information to support that belief. Arguments are reenactments of actual debates with more swearing mixed with regurgitation of often incorrect statistics.
The left and right is saturated with bigots. A fractional amount of voters even consider both candidates. To the left, Obama can do no wrong. To the right, if he says run, they walk - if he says walk, they run. In my experience, the only people who are informed enough to vote are those who consider voting bi-partisan, and who classify themselves as independent, libertarian, etc. This all goes back to why you see these points blanketed over all conservatives which I think is because these moderates don't want to associate themselves with the extremist nature of the right media. A moderate, even someone who considers themselves mostly Republican, cannot possibly seem partial when he is next to someone using religion as political justification and partial people don't like appearing impartial. Just know that just because someone votes Republican, doesn't mean they have tunnel vision and belong the Westboro Baptist Church any more than a voter of Democrat is expected to be on the newest season of Whale Wars.
