MJ Rosenberg has written another article on the Israel Firster smear, which has grown beyond him and which he is proud to lie and say that he came up with. You can read the article if you want, I'm more interested in this 6 favorites comment:
Zach and I see all kinds of logical fallacies employed by Israel haters (mostly because supporting the Palestinians requires your brain to go on long term hiatus), but this is one of the most blatant ones I've seen in a while.
The people in question are insulted by being called "Israel firsters" and this individual, and his 6 friends, take that as proof somehow, that they are guilty of it. And then he further insults their intelligence by arguing that if they "didn't know it was wrong they wouldn't feel the need to deny it."
This kind of confirmation bias is as flawed as it is ridiculous. If I were to write, "All Muslims are terrorists," and then used the large amounts of justified outrage spawning from that as proof that I'm right, I don't think I could convince very many people to see that my way. Only fellow bigots, I guess.
