I Was Baptised By a Baptist who talked my mother into having me, and gave her 7 Sutton Place to live in when she came to NYC to be a pioneer woman/socialite and organizer of cocktail parties where deals were struck.

I was later confirmed by the Anglican Bishop of Lausanne so the King of England is the head of my church.

Getting born is important to existence and you do not need Jean Paul Sartre or Simone de Beauvoir to tell you that.

Or Heidegger.
