Confront Idea, not People
Ire wrote a blog post that sparked a bit of excitement in the community, and one I personally wrote partial response of. They followed with another blog post in the wake of this "virality" (at least to the extent virality happens in this small space).
What particularly bothers me is the offhand mention of insults and threats. What gives? Insults and threats, really? That sounds incredibly mean-spirited, disproportionate, counterproductive.
People should be allowed to write opinions on their blogs, even if it ends up divisive or unpopular. Debates should take place in our own blogs, where idea is ruminated, dissected, reformed, clarified, exchanged, and most importantly allowed to mutate. Someone might agree, someone might disagree, someone might start a skeptic but eventually convinced, etc etc. This way, a conversation stays alive instead of one voice becoming a permanent edict that dictates the topic from then on. It may get heated at times, but never ever personal.
Personal attack is not a way to advance a discussion. It shuts down conversation by bullying a party into submission. This tends to happen a lot in online spaces, as we can see whenever an artist/writer/... steer a story into a dissatisfactory ending.
That Ire had to write a clarification post at all is a bit sad, a bit appalling. I'm sorry this happens to Ire, and if you read this, I apologize if I played any part in the attacks you received. I had wanted to send an personal message upon reading your latest post, but couldn't find a contact detail on the blog.
If you find a post you don't agree with, do not send the blogmaster personal attacks. Write your rebuttals. Of the idea, not the person.
