I guess that unless I'm willing to get four-square behind things like concentration camps for immigrants, I'm not a "real" 21st century Conservative.
Trump exploits the extremes. It's a gigantic reality show, apparently, except that the stakes are far more deadly dangerous than the public seems to understand.
I think Trump and the Republicans are warping the term. He is not and has never been a conservative of any sort. The Republicans aren't really very conservative any more either. As a party, they're sold themselves, like whores, to the wealthy elites who don't care about anything but getting their taxes lower. See how quickly and easily they threw deficit reduction out the window to please their donor base?
