I haven't seen many good arguments against Snowden either - but your comment here is a huge strawman. Just because you feel strongly about what Snowden did doesn't mean everyone who disagrees with you is ignorant/dumb.
I didn't say anyone was ignorant or dumb. I said they're not providing a worthwhile argument, but resorting to generalities and vague ominous implications.
I wouldn't call that a strawman. It's an explicit challenge to provide an actual argument, while showcasing a behavior that is not meant to be an argument.
strawman: "Their argument is this weak thing that's easily disproved."
this post: "I haven't heard a single actual argument from them."
