So there's this guy, these guys and these ones as well.
Taking a quick look around the other side you see these guys, people like this (yeah, that's the eugenics guy, who also routinely makes racist statements about both Jews and Muslims, whom he considers to be all "one race") and people like this who make YouTube videos like these.
They say unbelievable things like this and this and THIS AND THIS AND THIS AND THIS AND THIS AND THIS AND THIS AND HOST WEBSITES LIKE THIS... AND THIS...
...And they cry and whine about being "dismissed" when shown their own words.
When you're asked to show your evidence for your pet theory, and your reply is that "Philip Zelikow is a Jew," that is a racist statement. When your argument against the bailout bill is that it gives more power to "the Jew Banksters," sorry, you're a racist. When you argue that 9/11 was an inside job because it "helped Israel," you're at the very least race-baiting.
And if you're going to argue that water fluoridation is a mind-control conspiracy and that the government kidnaps children to push RFID technology, don't whine about not being taken seriously. You're a credulous, gullible dupe who has sold out every ounce of your reason and your skepticism to a growing army of t-shirt and DVD peddlers looking to make a quick buck.
If you are or act even close to any of these people, sorry, you've surrendered your ability to think and, hence, your right to be taken seriously.
