There's a simple way of dealing with that. Don't be a racist nut job. Have actual valid reasons for your positions and keep the outrage to a reasonable level.
Coming from a person of color, far too often accusations of racism are used to silence legitimate dissent and debate.
Having valid reason and articulable concerns will not be enough to protect anyone from charges of racism.
We shouldn't be allowing anyone to enter this country if they have been to a country with an outbreak of any hemorrhagic disease in the past 90 days. For now, that means certain west African nations. The people in Zambia are every bit as black as the ones in Liberia and THEY aren't letting Liberians in.
Obama himself isn't a lefty, he's a moderate right politician. It's just the racism that blinds so many right wing nutjobs to what Obama is actually doing.
Depends on your politics. If you're an anti-war lefty, there's not much difference between Obama, Bush, Clinton, Bush or Reagan.
If you're a small government righty, again, Obama, Bush, Clinton, Bush and Reagan aren't much different.
Me, I'm a fiscal moderate and a social conservative. There are lightyears between Obama and Bush, from my perspective.
