1) This is logically untrue. For one thing. "Anti-Semitic" refers to people not governments. It would have to be directed towards the Israeli people themselves not the Israeli government. An unfair attack on the Israeli government would be "anti-Israeli" not anti-Semitic.
For another, let's assume this is completely bogus. Let's assume for the sake of argument that it's a conspiracy theory absurdity on the same level of Obama was born in Kenya. Then let's change the facts around. Instead of "an [Israeli government] eugenics program" let's replace that with "9-11 was an inside job devised by the Bush administration", and "anti semitic" with "anti American"
If we do that your statement reads as follow: "Pretty much... hopefully more investigation will be pursued if 9-11 was an inside job devised by the Bush administration, but until there is evidence, acting like there is, could be considered anti American".
So how is this anti-American? It has nothing to do with the American people. It's purely a criticism - no matter how inane - of the government. In exactly the same way your statement has nothing to do with "Semitic" people.
2) There is evidence. The problem is that he (and it seem you now) have decided that little evidence means no evidence, and you've decided to turn the table on those using that evidence to decry them as racists. Do you realize both you and Qazaq have accused people of racism and bigotry for criticizing a government. This is a sad trope that unfortunately plagues basically every conversation I've ever seen about questioning Israel's questionable actions.
It makes it impossible to have a reasonable discourse on the subject and does nothing but solidify the opinions people already have about Israel. It's more knee-jerk than the knee-jerk reactions against Israel.
It's also so cliche that it appears that you, him, and other of the same position have arrived at this position, not because you've looked at the totality of the evidence and critically weighed the issue, but because you have an emotional disposition that you've allowed to be manipulated by the Israeli government's propaganda machine. That's why you're "drinking the Kool-Aid". You are ingesting what they are giving you without asking what is in it.
