Discuss the post, not the poster.
You and i can never be 100% sure either way, this is the internet. This has crossed from discussion into harassment by now.
Don’t drive people away for no reason.
And consider the 4 scenarios here: you were right or you were not; and he stays or he leaves. In one of 4 possible combinations, this is a huge loss for the forum. All other 3 are meh.
A bit of probing is surely OK, but harassment is not.
Back on topic please.
