In a free society everybody is entitled to his or her own opinion. However, just because someone has the right to an opinion doesn’t mean this opinion is right or true. And I believe that the right to have an opinion is not a protection from having your opinion challenged. In fact, I believe that in a free society opinion should be challenged and that not every opinion as the same weight/worth.
The opinion of an astronomer on the probable influence of the passage of an asteroid close to Earth, is much more likely to be correct than the opinion of an astrologer or someone with no knowledge of physics or science. And even where this astronomer to be wrong about the asteroid influence, his opinion should still have more weight than the astrologer’s and profane. That might seem strange, but the opinion of this astronomer is based on years, if not decade of studying the universe and how asteroid or other celestial object behave, his opinion is based on repeatable fact and information. The opinion from the astrologer is based on demonstrably false concept and there is no telling what the profane opinion is based on. You might counter by saying, but what if the astrologer’s opinion was right? It still doesn’t matter (unless the principles of astrology could be shown to be true, or even just workable) arriving at the right answer when you make a guess (uneducated) is just a coincidance.
Finally, based on this opinion should not all be given the same weight in the media, it is not showing both side to give as much time to creationist as is given to scientist. It might seem fair and unbiased, but it is very unfair and biased toward creationist. Think about this, their opinion is demonstrably wrong, is based on the words in a book with lots of demonstrably wrong conclusion about the world and held by a very small minority of scientist (strangely almost none of which are actually studiying biology). It’s exactly like having a medical show talking about birth and pregnancy and giving half the time slot to proponent of the stork theory of birth.
