This is, was, and always will be a meme. "Being your whole self" is just giving lolcow milk to people to use against you later, whether that's HR at work, fake friends to mog you with later, or as dirt/blackmail for online psychopaths to use against you. Being your whole self should be reserved for your closest friends or maybe only your lover. Otherwise you meet people at the level of retard that they're at.
I would not go on Kiwi Farms and tell my life story, and you shouldn't either.
OT: Everything online is ruined and I no longer enjoy anything. Socializing is a chore. Which sucks because I like talking to people, but the people are retarded. Kiwi Farms is nice because it filters trannies, gooners, and the worst autists (stronger autists will usually not get filtered but then have a thread made on them later).
