The real reason is that many of the self-identified “conservatives” would be savaged as RINOs if they posted on FR.
Is that the sound of a nail being hit solidly on the head? Why, yes it is.
One thing about Liberals - they always want to tell everyone else about how everyone is a Liberal, rather than discuss right and wrong, or the efficacy of policies, or why our economy is on track to collapse ([cough]Leftism).
Ideology is maleable. Liberals get mugged, and every so often, somebody like Reagan comes along and aggresively dengrates leftism and in both cases, the populace trends right. Conversely, when idiots in our party avoid confrontation and try to play nice to appeal to leftists, they push the electorate left. You don’t just fight on this battlefield - you mold it by your actions and your rhetoric. The populace are lemmings, if nothing else. Four more years of Obama should prove that to anyone. You don’t lead Lemmings from behind, or gently ask them to go in a direction. Anybody who doesn’t get that shouldn’t be involved in any leadership aspect of the movement.
But by all means, keep telling us to be nicer to our Liberal brethren, so the lemmings will want to like them too. Reasonable idiocy is quite fashionable these days, and Liberals do so approve of that.
