I specifically stick to monasticism because Christianity is the odd one out of all the abrahamic religions in advocating for monasticism, and monasticism started in Egypt which had significant enough presence of Buddhists.

As far as I am aware, Christianity is the only non Indian religion to advocate for monasticism or asceticism. It's really only Jainism and Buddhism that advocate for it other than Christianity (Hinduism picked it up from Jainism and Buddhism).

That being said, your reaction is exactly what the guy above was saying was an issue.

You conflate Buddhism with Roman polytheism. Buddhism is not dogmatic. Buddha is a man who saw idolatry all around him and quickly determined it was ineffective and false. A core part of Christianity is that God needs to reveal himself. Being before Christ, Buddha would not have known about the resurrection or that such a thing was possible. He made some observations and literally said if he was wrong ignore him. While many modern day incarnations of Buddhism are dogmatic and some have descended back into the very superstition the Buddha advocated against, the core story of Buddha is complete the opposite of Roman polytheism.

Again we see the parallel with Christianity where a bunch of people were marginalized for advocating against Hindu Polytheism, with Buddhism eventually winning the support of the great empire of the time (the mauryans).
