I've seen plently of reasonable criticisms of Perry come under personal attack.
For example I was called a liar by three different Perry supporters simply for pointing out Algore's liberal pro abortion history in the Senate in the 80's.
BTW I notice that you use the term "Perry-bot" in double quotes but you don't do the same when you use the term "Cain-bot".
There are attack-dog, bot-like supporters for all candidates. Posters don't notice the ones on the side of the candidate they support.
Here’s what I noticed. Before Cain’s rather nasty turn over the rock issue, I was supporting three people—Palin would have been my first choice, and Perry and Cain were about even. I was never attacked by anyone when I said that Cain was one of the ones I supported. After the rock issue, and with subsequent remarks he made, etc., I dropped support for Cain. Palin dropped out, leaving only Perry. I can’t tell you the horrible comments directed at me personally for saying I didn’t care for what Cain did about the rock—some even suggesting I live in an area where cousins marry and people walk around with their knuckles dragging the ground. And then there are those who simply state that anyone who supports Perry is an idiot, a moron, you name it.
So yeah, I’m a little tired of it, and not expecting it from people I used to consider conservatives. I don’t see why a conservative can’t have a reasonable disagreement over who the nominee will ultimately be, without resorting to those kinds of tactics. If anyone wants to rip apart the conservative base, that would be how they’d go about it.
