I see it this way. Offline, it is harder to be oneself (unless you live in a culture where your self is defined by community; American culture is different so I never experienced self by community). Anyway, we are constantly being chameleons because we cant be are whole selves at work, school, even our family doesnt know EVERYTHING about us. The thing is, a lot of the time we can monitor our behavior and speech on the spot. So, our true nature is hidden by constant replay. Its human.
Online, its a little simplier to be yourself because you havw time to develop a full thought without needing to censor it because of body language and differences in others reactions known and unknown to self. With that, we can tell more into your true nature. Unless what you are posting is a fake you and dont know it, the nicd JW offline is inwardly hoping eveeyone comes to Jehovah by the words he choses that he would not otherwise say offline. Relationship with others (how close one is) also let us feel we can "get away" with being our true self because we arent responsible for what we say because we are only talking to strangers. Then we get upset when we break the rules. Fake selves dont need to defend
themselves.
It could be another facet of ourselves. Online I do talk a lot and do have stubborn periods. Not much different offline. Online I can be my reflective self, learn new things, and speak via my values that I find harder to do in person.
So, it really dependa on the person. I do believe we have multiple personalities in different environments and people we speak with. Some more true than others. Its human nature.
BONUS QUESTION: Why do so many of us seem to assume that, when a person displays negative behavior, that's their true self -- even if they mostly display positive behavior?
Religion, from American culture view. Our trueselves are inherited with sin and our our heart, if we found god, inherited with gods blessings.
People are more influenced by negativity. Flight or flight. We remember intense experiences more and unless one has a positive intense experience (like god), mundane ones.
I dont see the inherited-sin view. I just find when people show tbeir true self, their essense, they are more alive. When they dont, its still their true self just its helpful for it to be addressed as we know the difference between spiritual sadness and spiritual depression.
