Sure but it's really not that hard to keep things under control in the work place. I have my own opinions, sometimes I share them at work, sometimes people may disagree, however, I don't "rack up multiple HR complaints" like this guy did.

I disagree. The OP was essentially arguing that being offensive to a group of people is okay if that group is a minority. I was simply demonstrating how absurd that argument is when directly applied to a specific group of people.

I honestly don't even understand your analogy, it isn't similar to what I was saying at all. It is pretty safe to assume the author of the article was saying offensive things to a group of people, not having an unpopular opinion about something in general. These are two very different things that any sensible person with empathy would be able to differentiate. So, because of these inherent differences, your slippery slope argument makes no sense and is not be reflected in actual social interactions
