Atlantis1star only arrived on the HP in March 2010, but it didn't take long for him to join the upper echelons of the anti-Zionists there. He doesn't exclusively talk about Israel, but it is pretty clearly his area of focus. Like many AZs, he spams the same talking points over and over, as you would find if you looked at this profile above. As for abusive comments, it is mostly claiming that Israel is a "terrorist state" akin to Nazi Germany.
Most notable is that he spams a paragraph in which he claims that "the Jewish Lobby" is "a Fifth Column" that brought the US into wars with Iraq and so forth. You can read the comments below for yourself. Atlantis1star has about 600 comments and 62 fans.
