If we were happy or not, why does that even matter? It doesn't change anything, we didn't contribute to it and America caused it through their foreign policy choices. Seems like kind of a pointless line of inquiry.

Only around 2-3k people died there, compared to millions from covid or millions we killed in Iraq and Syria, or tens of thousands dead annually in the US from lack of healthcare. Nobody freaks the fuck out and demands memorials for those deaths, so why are they deemed so much less important? Because it's not actually about the deaths, that's a smokescreen. It's about the wound to America's collective national ego, its self conception as untouchable master of the universe. That is the actual casualty of 9/11 that people mourn and cry about. Oh, and as another user pointed out, many of those 2-3k dead were cops and finance ghouls so of course we have to worship their sacrifice or whatever because Americans are bootlickers
