[He Rides A White Horse]

The most common one in use now is of course multiculturalism, which have managed to achieve hegonomy over bothe the (obstensively non-Marxist) Libertarian and Republican parties.

Try saying what you really mean next.

Which is that the Libertarian and Republican Parties are doomed because they have fallen victim to "multiculturalism", which in your usage undoubtably means they admit people of color.

Unlike your pure, "non-multiculturalistic" party, whatever that may be.

I can hazard a few guesses, however.
