Should have stuck with "ha ha" as this is quite possibly the worst defense of an absurd opinion that I've ever read. First, you're simplifying the effect Bin Laden has had on the US to hilariously simplistic levels just to fit your agenda. We are at war with Al Qaeda and we wouldn't be if it weren't for Bin Laden. This has had a hugely negative impact on the US. And the way you gloss over the impact of 9/11 is akin to saying, well Hitler just killed a few people and invaded some countries. Clearly the effect of the bombings was much worse than you imply.
But the main problem is that you're comparing verifiable facts with your opinions. I mean it's unquestionable fact that Bin Laden had a significant negative impact on the US. It's debatable that Walmart even has a net negative impact on the US at all.
Now, is it possible that your statement is true? Yes, but flatly stating it as fact is silly.
