This is the exact same argument Bin Laden used for 9/11; that the US civilians were culpable due to their votes and taxes supporting what the US government was doing.
Correct! And he hit a nerve laying this logic bare, which is exactly why The Guardian took the unprecedented and absurd measure of removing his manifesto from a decades-old article when it went viral a year or 2 ago. Lest the populace get to see things for what they are. At the same time unmasking their veil that despite their pretenses, they're just as much of a capital interests-captured rag as their "competitors".
It is absolutely possible, reasonable, and normal to be unhappy with US foreign policy in the Middle East dating from before I was born, but also believe I have no power to change course there.
I'm not the "both sides are the same" kinda guy, but we realistically only have choices between Democrats and Republicans here, and I'm not convinced things would be meaningfully different in the ME if some US elections over the past 50+ years had gone the other way.
As a personal example: I was eligible to vote in my first US presidential election at age 19, in 2000. I did not vote for Bush. He still won, and still started a war with Iraq under false pretenses. I was utterly powerless to change those events.
So I'm not sure what nerve was hit here, because, "I'm going to attack regular folks in another country because I don't like what their government is doing" is still just as cruel, cold, and ineffective, regardless of the targeted country. Ultimately bin Laden failed: US foreign policy in the Middle East has not changed in ways that I expect he'd be happy with. Perhaps his consolation prize is that, due to the reaction to his attacks, the US is a lot less freer than it was before; not only did the government use it as an excuse to curtail freedoms, but the actual citizenry started prioritizing some higher measure of safety and security over freedom. But I don't think that makes the world a better place, even if bin Laden might have considered that particular aspect of things a success.
