Well, sorry... but I think he sounds like a jackass in general. I mean, you go through a break-up... sure it hurts, but you just MOVE ON... like a damn adult. That kind of angry, fixated behavior where you go to great lengths to try to "damage" your ex professionally... what in the HELL is that? Normal people don't behave like that. That's FAR more alarming than any of the gun stuff IMO.
Here's where I'm confused though... are these articles saying just the account was fake.... or were the pictures fake also? Because if she was willingly putting on an SS uniform, well... my sympathy for her would plummet, too, quite frankly.
But, either way, he still sounds like an obsessive jerk, and I, for one, don't feel compelled to defend EVERY gun owner - certainly not the ones who run their lives like a train wreck.
