@TomFromIsrael,
1) There are almost 326 million people in the United States.

I'll be generous and say you've seen 1,000 people bitching online. That's 0.0000036% of the US population. Increase it to even 1 million Americans (and that doesn't even begin to take into account people you may have seen twice or that you think are American but aren't) and it's still less than 1/3 of 1% of the entire US population. It is statistically insignificant.
2) You're obviously not everywhere online. No one can be. I put it to you that you're seeing this because of the places you're hanging out at - which are clearly not A2K, I might add. If you're seeing that sentiment here, it is far from the majority's POV.
3) Confirmation bias/looking for such statements online. When every problem looks like a nail, then every solution looks like a hammer. When you only go looking for people from America bitching about Israelis, then that'll be all you see. Go to the forums for Toyota, or the Fox News website, or the Washington Post's website, or CNET, and tons of other places where people hang out online, and that won't be all you see.
4) Make a topic about how much you hate Israelis (and yourself, apparently, but I'll leave the armchair psychoanalysis to others), and you'll attract people who'll bitch about such things. Make a topic about how you love lime jello and you'll attract people who'll rhapsodize about it.
So, you got any basis for your statements other than antisemitism?
