If you're looking for an area on which conservatives do not allow dissent, try the issues of race and Jews.
Joe Sobran, Sam Francis, Kevin Lamb, Jared Taylor -- all these men were hounded out of conservative publications for taking politically incorrect stands on those topics. On race, your average conservative is about as open-minded as your average liberal, and on Jews, they're even worse (all races are equal, Jews are more equal).
Conservatives live in perpetual fear of being called racist, so much so that they design their entire platforms around desperate attempts to appear "non-racist" or "anti-racist." The result is that they're easily whipped around: just threaten to call them "racist" and they fold like plastic wrap. As Alex Linder has noted, "racism" is just conservatism with balls. Conservatism, is, well, neutered.
It's all a load of bullshit. You could have the lowest taxes, the strictest abortion laws and guns for all, but if you're sharing turf with 30 million Mexicans, you may as well be living in Mexico. Put another way, when Tyrone is raping and dismembering your white daughter in the name of "civil rights," a six percent cut in the capital gains tax ain't all that much to crow about, bow-tie boy. Whites need to realize that no ideology will save them, save white nationalism.
