In my experience, out of every 10 people you try to educate on trans issues on the Internet, just one of them may be open to persuasion and intelligent dialogue; if you're lucky they might even come away reconsidering their views.
The other 9 out of 10? They're those monkeys from the Infinite Monkey Theorem: banging away at their keyboards, trying to figure out how to type up the complete works of Shakespeare.
Any commenter who fails the Monkey Test (as I call it) get short shrift from me.
