lhb, I reckon you're better off steering well clear of social media. That's what I do.
Truth be told, I've never bothered with it myself. Facebook, twitter, none of it. Heck, i haven't seen the new sequel films either. I'm just not interested in any of them. (I will always have a place in my heart for the original films. I enjoyed the prequels too, though I've not seen 'em in many years)
However, I've been following a few Youtube channels covering a lot of the goings-on. It's not just the twitterati outrage merchants, but also a few like-minded journalists, bloggers an' such throwing out the usual insults; toxic manbabies, basement-dwellers, fanboys, people of low morals and questionable character - acting pretty much like the bullies in those '80s flicks. Casting aspersions on fans just because they don't like a particular movie or how the characters were handled. I've seen similar sentiments with the new Ghostbusters trailer. There's one chap over at Wired.com moping about how the new flick shouldn't reward regressive fanboys, or something along those lines.
I don't like to use the term SJW, (I think it's been overused to the point where it's lost all meaning, like a lot of internet buzzwords) but i think that overly sensitive crowd, along with a few attention-seeking muckrakers, seem to spout the most vitriol from what I've come across. A lot of the nerd rage I've seen seems to be in response to that most vociferous lot.
For what it's worth, I'm no fan of them either. Bunch of self-righteous judgemental whiners, the lot of 'em.
