If you were in the same room as this person, and he poked you (in some non-sexual part of your body), how would you react? Would you laugh and poke him back?
Probably not. Unless you want to sexually encourage him. Because, in “real life,” poking someone (who is not a family member) is a sexual gesture.
Would your reaction to this (real) poke be deemed an “over-reaction?” I don’t think so.
Why should our online reactions be any different than our “real” reactions?
Suppose that, tomorrow, Facebook replaced the word “poke” with the word “grope.” Everything else was exactly the same, except for this word. Would you be accused of “overreacting” if you didn’t choose to “grope” someone back? I doubt it.
Suppose, instead, that Facebook replaced the word “poke” with the phrase “gave you a thumbs up.” Would you have any reservations about returning this gesture? I doubt it.
Words mean things. As we “digitize” our lives, we must not loose sight of the meanings of our words. There is a difference between giving someone a thumbs up, and poking him, and groping him. Just because we express these gestures digitally does not mean we do not express them.
This is why I have never “poked” anyone on Facebook, and I have ignored all “pokes.”
