If people wish to put personal information online it is of no concern of mine. They are supposedly grown adults, and I will therefore treat them as such.
As for me, I have a very specific, carefully curated persona that I expose on Medium, expounding on my passion for film, literature, music, and such. I'm rather old-fashioned in my belief that certain matters - how I vote, my income, sex life, for instance - should remain private. Again, this is for me personally. I make no judgement on others, and wish them all the best.
