It seems to me like almost everyone claiming that GPG email is totally unsafe crap is not actually using it much. Or even at all for day-to-day communications.

By which I mean they don't actually know what it's like to use it daily in 2018 and the reasons they cite sound kind of wacky to someone who does.
