Sorry you had to go through that, it can be quite traumatic. I still agree though that in general Argentina is safe. The most dangerous thing about Argentina is the women. One must excersize extreme caution with them.
I will admit that most Argentine men walk the country with a facial expression that makes me wonder whether they're pissed off, confused, or their faces are just naturally like that, but once you scratch the surface I've found Argentine men to be gentle, soft & overall pleasant to be around. For this reason I don't think it ever has been or ever will be a violent country. When I was with my Brazilian ex and she'd say "let's go out drinking with my friends/family" I'd have to kindly invent ways to basically say "wait.... let's talk about this first, who are they, what do they do professionally, etc". Never had that problem in Argentina.
