> I don't see a justification for spying on a co-worker
Hmm. I don't have an examined opinion on this, outside of general hesitation to go looking for problems for reasons such as confirmation bias and whatever the name is for what self-fulfilling-prophecies looks like this in kind of situation. Well, and maybe that if you're looking for justification you've already messed up. Just because you can somehow find a consolation prize doesn't mean you should have done something in the first pace.
Because you're using your biases against people who think differently than you to justify immoral behavior.
Edit: You don't need to tolerate bad behavior, but it goes both ways: You can't justify bad behavior in the name of policing other peoples' dumb actions.
Because I think you need to have more empathy for why people align themselves with causes you disagree with.
If you have the time, I suggest reading "They Thought they Were Free," by Milton Meyer. It's a well-known book that tries to answer why generally "good" people joined or supported the Nazi party in pre-WWII Germany.
It's been about a decade since I last read it, but I keep it on my shelf. What I remember, though, is that the reasons why Germans joined or supported the Nazi party vary quite greatly. I remember one passage about a man who basically liked dressing up in Nazi uniforms because he loved pageantry of Nazi rallies. Another was about some Jewish children who saw a Hitler Youth parade in a movie theater newsreel, and really wanted to join.
It's well worth the read if you need to understand why hate groups are so attractive to some people. (Or, to basically "examine your biases" towards people who you have "legitimate disagreement")
I don't follow? Maybe try rephrasing?
> can be a racist / homophobe in secret
I can kind of see that, but, the KKK wears hoods?
