That's a very obvious strawman. If you downsize it to the level that GP alluded to, asking if Trump's voters are jerks because they voted him into power, I guess a non-negligible amount of people would agree.

No, it's not the people. It's some people that voted Likud in. Much like some Americans voted Trump in. Where's the strawman?
30% of Americans even today support Trump. So one would be right to claim that 30% of Americans are jerks.
