The phone call tape that they played on the news (supposedly on Steny Hoyer’s answering machine) had so many expletives that you could barely tell what was being said. I don’t know ANY pro-lifer (this caller caled him a “effing baby-killer” among other things) who uses that kind of language in ANY context. Sounds more like SEIU/ACORN trying to whip up the kook fringe.
I didn't hear the tape, but I cannot believe that there exist large numbers of conservatives who would engage in illegal death threats, and like you, I know of no conservative who would speak in the manner you describe.
I hope all these phone calls are totally traced and that ALL the perpetrators are identified and exposed.
I suspect that there are very few conservatives involved, IF any.
