If I could go through Scripture and figure out that the arguments people use to "prove" Mary had other children is baseless garbage anyone can.
Those who insist Mary had other children are under a strong delusion and don't even want to know the Truth.
It's like a huge herd of Ray Charles clones, all blind, wearing hip shades, each sitting at their own little piano with a huge smile, and swaying in time with the music as they each belt out their own favorite tune.
The plain words of the gospels declare that Mary had many children.
The strong delusion is your own! Deny the scriptures at your own peril. There is no basis to believe anything else.
