No, you are not a catholic. A catholic is a person who has faith in a specfic god (the Abrahamic god) and in a specific religion for worshipping that god (catholicism). You very clearly have neither faith, so you cannot possibly be a catholic.
Well you are wrong there. He can indeed identify with being a catholic because of his upbringing.
It's called Cultural Catholicism, where you identify with the Catholic traditions without actually practising the faith.
