Because the destruction of our country brought about by the Dems and RINOs is not at all 'extreme'.
They, the Dems and GOPe, move further and further left. We remain solid but the further left they go, from their perspective, we look more and more extreme.
But it’s not us that’s changed. It’s them. So when someone comes along and represents many of our views (build the wall, for example) to them, it sounds extreme.
This does not excuse their behavior, just helps explain it.
I don’t see what’s so great about being a conservative. We have no leaders they are all traders. I’m all for Trump. Cruz can be his VP.
