In the 1950s there were people in the United States who believed the world was flat, despite the fact that belief had been proven wrong centuries previous. But they were not given time to vent their belief in the national media, because their belief was not only ignorant, it was wrong—factually untrue.
After the first Americans walked on the moon forty years ago, there were many in this country who believed the whole thing was a hoax. They weren't given a voice on news shows in the national media because not only was their belief ignorant, it was factually untrue.
In the 1970s there were those who believed the world was created as stated in the Old Testament and that evolution was a hoax. But they weren't given time in the national news media to air these beliefs because they were not only ignorant, they were factually untrue.
But then something happened in the 1980s and '90s and '00s. First Ronald Reagan got elected with the help of a Republican base of rightwingers that he had helped create, and functionaries like Lee Atwater and Roger Ailes helped perpetuate and grow.
Then under the Gingrich-led Republican Congress during Clinton's administration, catering to the rightwing of the Republican party wasn't just a strategy but a reality. The rightwing had become the Republican Party, at least in Congress, and any leverage could be used to oust centrists and moderates including questioning their religious beliefs. It became a badge of merit among many Republicans to scorn a lot of scientific fact as "relative" (of course they used the opposite claim against liberals in the area of morality). They deliberately misrepresented—leading to much misunderstanding of—the use of the word "Theory" in "The Theory of Evolution" to imply it hadn't yet been proven, though it had. Just as the "Theory of Gravity" was proven.
And of course under the last administration the capitulation to the rightwing nuts was completed, no matter how ignorant and factually untrue, any rightwing nutty idea had to be catered to for fear of attack from the right and being cutoff from access to the White House (as well as being fired by the mostly rightwing owned media).
Which brings us to the present, where despite the factual reality of Obama's birth in Hawaii, those who question this FACT are not only given time and presence in the national news media, but so is every crack pot laughable red herring raised by the rightwing nuts. As in: Obama's health plan is socialist! The same argument Ronald Reagan made in the 1950s as a spokesman for the then marginalized right. He claimed that the creation of Medicare would lead to not just "socialized medicine" but to the government telling you where you would work and live, etc.
None of that came true of course, but the same arguments are being used and this time given not just a fraction of air time, but supposed "equal time" (although what is meant by that now is every time a centrist or moderate makes a factual point a rightwing nut has to be given "equal time" but not a leftwing perspective.).
If all these rightwingers don't believe in the climate changes that are factually occurring (rising seas, thawing tundra, melting glaciers and ice caps, stronger storms, etc.) fine, let them talk among themselves, but don't give them media time to pretend their perspectives have any scientific validity. (The only scientific argument is over what it means and how much humans are contributing to it, and even there the general consensus is pretty consistent.)
If the rightwingers don't dig socialized medicine, or what they call that (any plan that has the government involved in any way), then if they're veterans, like me, they should refuse any use of veterans benefits or veterans hospitals etc. And if they're on Medicare, they should refuse that too. If they're in Congress, they should refuse the plan used by our "representatives" and instead be faced with the same kinds of choices most working citizens of this country are faced with when it comes to health care as now practiced (and let the right wingnuts not be given media time to claim our system is the "best in the world" since factually, judged by most healthcare or healthy citzenry statistic, we come in way behind most and often all other "industrialized" countries and even many "developing" countries).
