I have a hard time imagining that - Gene has his own opinions, but isn't more caustic in expressing them than many others here are. I've seen what I consider to be some amazingly ignorant things posted here, as well as some extremely immature things, but I have yet to see anything said that's worthy of silencing the offender.
To be fair, I know plenty of lefties that are both principled and consistent in their views, despite that I may disagree with them. What I have trouble with are smarmy declarations and condemnations that seem to be tossed out without any consideration given to consistency - for example, speech and expression can not and should not ever be abridged, but someone needs to shut those people praying in public up because I shouldn't have to listen to it. The glaring inconsistency in that is often overlooked by many, and I've never been able to understand - or accept - that line of thinking.
