Your framing is interesting. You may feel that you can’t change who you are in real life, but people have a choice on how they behave online (or choose not to engage at all). So you could choose to be nice (or at least not a jerk); I’m pretty sure you wouldn’t get people writing to your employer complaining. I’d argue that if you know you’re sometimes a jerk, it’d be less stressful for you and others if you didn’t bring that energy online.
