He says we are regenerated after we believe. He is saying that Nicodemus had to do the same thing. By deduction, that is what he is espousing.
No it is not what he is espousing.This is what Calvinists do set up these false dichotomy's as if there are only two options. It is never the case and Calvinists do not have deducing skills as good as they think they do. What you end up doing is misrepresenting others and creating strawmen so you can knock them down.
What you need to stop doing is telling others hatt they are saying or what they mean. Listen to what they say they are saying and what they say they mean and then go back that. Disagree with their words but do not create your own set of words for them and then disagree with it.
No one needs you to tell then what they have said.
