Many rightwingers are anti-science, or at least speak as if they are.
However, this seems to be mostly involve issues related to important economic issues (global warming) or religious issues (evolution.)
Over the last decade, there has a lots and lots of planets discovered orbiting other stars.
Amazing! Not too long ago there were no known examples.
I do not believe this has been decried by any rightwingers (or if so not very many.)
I can see no economic interests who would have a reason to stir this issue up with paid propaganda. Maybe it is just a matter of time before some religious leader decides to way in on this "hoax."
However, I suspect this will not make it to the top of the anti-science crusaders list, unless and until signs of intelligent life are found out there.
