This is getting down-voted but honestly I agree. Silence is a professional courtesy when it comes to certain ideas. For instance, I don't talk about how I find certain parts of 4chan incredibly hilarious. As a black man, I'd definitely have co-workers blow up if I mentioned this at work - granted they feel more than entitled to talk about all sorts of things that I wouldn't even talk about if I was at a bar with friends (fringe lefty politics and sexually explicit things).
