What? It's true, the current main threat to Amazon in the US is Walmart. I stand by my argument - you're disparaging me while providing zero evidence to back up your argument.

You know what a straw man argument is, right? It's on Wikipedia if you don't. The straw man that you constructed is that the "activists" would just switch to Wal-Mart. Your argument falls apart with that assumption. I believe it to be a safe bet that anyone that quits buying from Amazon because they mistreat their highly-paid upper middle class workers sure as hell isn't going to be shopping at Wal-Mart which abuses minimum wage workers who don't have nearly the job mobility of a software developer. In other words, why would you think one would switch to shopping at a company who exploits workers who are worse off than the ones at Amazon?
