Being scientific and open to ideas does not in any way mean you "have to" accept every idea. I do not have to be "open to others" when their perspective is clearly clouded by a government intelligence operation in direct opposition to the 9/11 Truth Movement. That is like saying I have to be open to the crazy stuff being posted here on DP like the "giants" thread today. Every photo and/or skeleton has been proven to be a fake. I don't have to be open to a preposterous idea with no evidence.
"In the beginning of a change the patriot is a scarce man, and brave, and hated and scorned. When his cause succeeds, the timid join him, for then it costs nothing to be a patriot."--Mark Twain
