The fact that one can post under a pseudonym allows many people out there to spew vitriol just because they can.
I agree with him. It's the self-righteousness of many modern commentators that annoys me so much, and the continual need on both sides of the spectrum to find thought criminals and insult them instead of actually discussing anything. And people with sincere, moderate views are generally ignored or attacked for not being sufficiently extreme. This is, frankly, a great time to be a crank or a neurotic with an axe to grind, and the internet only makes it easier.
By the way, Nerd's Feather, what side do you tend to take, if you don't mind me asking? I've never noticed that you fell on any particular side, but I may have missed it.
On a slightly different note, it occurred to me that I've never heard of either MacFarlane or Correia (despite his claim of shifting a squillion copies) before. I have heard of Alastair Reynolds, though. I doubt there's anything much to be made of this, except that it's probably more productive to focus on your writing than wade wholeheartedly into the "debate". Besides, space is a big place. There's room for everyone.
As far as the binary/non-binary gender issue goes, I'd probably describe my own feelings as a more moderate version of MacFarlane's. I do really want to see more of that too, but it's not something that makes or breaks a story for me, as it evidently can be for her. But I also found Correia's reply to be as misdirected and unnecessarily bilious as Reynolds did--a tantrum worthy of a child, really. And some of the comments I've seen are downright bizarre--alleging MacFarlane is "forcing" things on them--this via an opinion piece posted on a blog, which last time I checked had no official policing capacity.
By the way, do you have a link to the text in question? I've read a post on Correia's blog, but have no idea if it's the one referred to. (I tend to doubt it, if only because while it's written in a (probably deliberately) snarky manner, it doesn't look like a tantrum to me.)
Trouble is that the above is an ad hominem attack where you go from misdirected and turn it into a opinion about him having a child's tantrum.
Saying something is 'a tantrum worthy of a child' is not, strictly, an ad hominem attack. (Saying "Joe Bloggs, as usual, is throwing one of his trademark tantrums" probably is.) The key to identifying an ad hominem attack is deciding whether the target is the person or one of their specific statements.
Sorry, but you are inferring an ad hominem attack, not seeing one. Sometimes adults do throw tantrums worthy of a child. Pointing this out is not calling those adults children. (And the way to defend the person accused of throwing a tantrum is to point out why it wasn't a tantrum, not accuse someone of using an ad hominem attack.)
