Science denied

Advances in science have no doubt contributed to a better world, and shown how important it is to rely on science to protect the Earth we all live on, for now and for future generations. Not only has science helped us understand better how things work, and why, but has also dispelled old superstitions and pretty much done away with imaginary fears and among other things pulled religion down to earth, so to speak.
It is therefor puzzling why science deniers even have a voice in this matter! Those without a science background or an understanding of science, and who instead denounce it all, should not have a voice and should not be taken seriously. This is not a case where we all have a birthright to equal say! If you don’t understand it, keep quiet and listen to those who do.
It is like a math illiterate who denies math because he doesn’t understand it and feels that he has a right to fight against its logical concepts and deny it’s power.
Or someone knocking a ball game without understanding the rules and how it is played.
Or, heaven forbid, like someone without a fiber of governmental background or understanding of how a society is supposed to work for all, is being put in charge of it, despite advertised plans to destroy it! That could never happen, could it? At least not in a society with intelligent voters who have some sense of what they are doing, – or what?
