My point is that a teen's behaviour doesn't reinforce the criminality of his government, but is mostly orthogonal to it. I can see perhaps there's a monkey-see monkey-do argument that does link a teen's behaviour to his society's, but Israelis are not fond of literal Nazi iconography, so I don't think that applies here.

If you try to use sketchy arguments like this to reinforce your opinions about Zionism, it only opens you to attack. Please, try to keep a level head, or we'll all look stupid. Rather than trying to guess if somebody is an apologist based on the consequence of their argument, maybe check if the premise is sound instead like a rational person.

(Aside: I also disagree with you about teens and self-understanding -- I do think a lot of teenagers are mature and self-aware; my point is that it's a high-variance distribution really.)
