It’s a strong gut feeling. αnσnymσus people who act the way he does don’t deserve the presumption of being a Catholic. He needs prayers.
So there is nothing he said that is against the faith, it is just your "strong gut feeling" then because he said things that while not heresy you considered uncharitable? Then say he is uncharitable, but not a non-Catholic. The way you said it was very rash in my opinion. When you accuse someone who professed belief, of being a non-Catholic, you should have footnotes. He does not support abortion or ɧoɱosɛҳųαƖity, like many supposed Catholic people do.
As the monk said when he was called a fornicator, he said "I am guilty". When he was called a thief he said "I am guilty". When he was called a murderer he said "I am guilty." When he was called a heretic he said "No. I am not a heretic." Why did he admit to all those sins yet deny being a heretic? Because to be a heretic is not a normal sin, it severs one's connection to God in a way greater than other sins.
So without proof you declared your fellow Christian a heretic, one of the worst possible sins, and cast him outside the Church. I know you are used to judging Pope Francis and the Bishops and cardinals and priests as heretics because they believe in Vatican II, but here you are judging another man who professes to believe as you believe to be a heretic. Rashly done. You are trying to kill his reputation, even denying his faith, for no good reason while claiming to be above him and being the charitable one yourself. Pray for him indeed.
If you do have evidence for his heresy, please provide it and we can read it, if not, please be quiet. It would be fair to say he is breaking the forum rules by making new accounts instead of accepting his banishment, but that is not heresy, and he is not the first person to do it.
