I think, with the exception of people being internet Trolls, that most people are very much themselves online. If anything they are more themselves because some of our inhibitions are down - which allows someone's true self to come out.

I'm much more assertive online than I am in person. I'm not (as) scared of confrontation online than I would be in person for various reasons, the biggest two being that I don't SEE them and that I can take my time writing things. Does it mean I am going to be really rude or cruel? No. That's not who I am at my core.

We can only base our responses off of what you show us here - and your words here are aggressive frequently, even if you don't demonstrate that aggressiveness in person. Very few of us are such excellent liars that we consistently maintain two very polar personas - to use my assertiveness as an example, in person I come off as much more passive... with some exceptions. My assertiveness will come out when I am advocating for others (strangers or people I know). I quietly take care of my own needs but it's in a passive manner.. until I'm backed in to a corner and have very little choice left. My coworkers have never seen me being assertive for myself, but they certainly know that I am on the behalf of others as it's the only time people hear me speak up.

I think that is basically what everyone has been saying Shadix - that who we are online is still very much US just without all of the inhibitions. So... the aggressiveness you show here? It's in you. It likely does show sometimes in your behavior in person, even if you aren't aware of it.
