I was born in 1990, to an intentionally unmarried couple.
When they wanted to have me baptised six months later, they ran into some opposition.
The church refused to baptise me, since my parents were “living in sin”.
They did manage to find a different church to do the job, but that should have been unnecessary.
Now, my parents had never been that religious even before this event, so I don’t think they had ever any plans of filling my head with religiosities, but I think this event really sealed the deal for my non-religious upbringing.
