Define "far right". Because I find you tend to define it rather differently from the rest of us.
Do we need to hear from homophobes, racists, and other bigots? Nope. Do we need to hear from actual conservatives? Yes. The two are not synonymous.
I think there is always room for a voice that urges us to make careful use of resources, recognize the value of the private sector, and keep government involvement in our lives and in the private sector to those areas where it is necessary and minimally invasive.
That's the best of modern conservatism and I wish the GOP and our own CPC would recognize that and stop playing footsy with the religious right, white supremacists, and other groups whose agendas are often predicated on fear, hate, and control of The Other.
