I don't remember name for this logical fallacy but I can think of a simple way of demonstrating, by rephrasing your comment. Vaccines don't cause autism by Dr.

I don't remember name for this logical fallacy but I can think of a simple way of demonstrating, by rephrasing your comment. Vaccines don't cause autism by Dr. XYZ >Written by 'XYZ', a long time 'Vaccines Support' party member that has always been very pro-vaccines. So of course he thinks 'Vaccines don't cause autism', because it goes against his long held belief that the 'Vaccines don't cause autism'. Just because someone has been in a 'idea camp', it doesn't automatically disqualifies their arguments. I don't really care about the topic, but this type of comment is my pet peeve. Attack ideas not people.
