I stopped reading Card like 20 years ago. It just didn't work for me. And there's so much other great stuff out there (whether Lit'ry tomes or mindless space-battle skiffy) that Card's fiction simply fell off the list. So, I can't say that I abandoned him for publicly stating his own views.
But he seriously creeped me the hell out back in 2004 with his extensive treatise against homosexuals & their fellow travellers:

His defenders can put enough spin on it that wormholes would be spawned like maggots on a dead horse, but the fact is that he calls for armed insurrection to put down the "War on Marriage." A Card passage not in the above essay sums it up:
Regardless of law, marriage has only one definition, and any government that attempts to change it is my mortal enemy. I will act to destroy that government and bring it down, so it can be replaced with a government that will respect and support marriage ... .
For a guy who makes a living from writing, it's kinda disingenous for him to claim he's a pacifist advocating for peaceful change through the democratic process.
