Thanks: I just spent a couple of minutes googling and do not feel a better person for the experience. And it only magnified my disdain for a particular vocal portion of the JS community.

NodeJS is a scary scene. I'm all for being vocal. But this? These are emotionally unhinged people. "Dog balls"? Yes, roughly half of all dogs have balls. Dog balls are curved and do look roughly like parens if you squint the right way. Do I personally think you should invoke imagery of canine reproductive organs in a professional setting? Eh. No. It's unprofessional. Should it be absolutely socially criminal? I don't think so.

I can certainly see your point on professionalism, although I will note that having watched the footage quite a lot of the audience appeared to find it funny.

That's true, but mob (majority) rule is also scary:

'In Federalist Paper No. 10, James Madison wrote, “Measures are too often decided, not according to the rules of justice and the rights of the minor party, but by the superior force of an interested and overbearing majority.”' - http://www.capitalismmagazine.com/2009/04/abhorrence-of-demo...

Just because lots of people laughed doesn't mean they're correct. Could just mean they were uncomfortable.
