Not every scientist agrees with Evolution, or with climate change either. The scientific community works through peer review and general consensus. When the vast majority of scientists agree on an topic based on peer reviewed research, it becomes the scientific view.
When you attack this process, you are attacking science.
Let me ask you this question... what would it take to change your mind
about either GMOs or colloidal silver? The scientific consensus already exists. There are peer reviewed papers, research, and reputable scientific organizations including public organizations and Universities, all saying that you are wrong.
I go by the scientific community... if there is new peer reviewed, repeatable research that is accepted by a variety of reputable organizations saying that my view is wrong... I change my mind.
The problem with ideological beliefs is that they remain steadfast no matter what the evidence or the experts say. Rather than accept what scientists say, you call them "conmen and pseudo scientists".
The only difference is whether they challenge your ideological beliefs.
