Me? I try not to. I don't like windows but I don't preach about it. C++, Java,C#, etc. I like em. I prefer Python. But I don't preach about it. Python 2 vs 3? Who freaking cares? Just get stuff done. But I don't preach about it.

I just go about getting my work done.

I think my only true religion is that I want open protocols. Chat, home automation, auto, etc. should all use open and documented protocols.
