No...none are true.
Jesus was conceived immaculately. Mary was a saintly woman just as Abraham, David, Isaiah were saintly men.
But saintliness (obeying God by His grace) does not equate to being immaculately conceived.
because it’s a bit like trying to talk someone into admitting that his/her mother is flawed
I like Lewis, but it's not the same simply because Mary's not our mother.
Common error. A lot of what Protestants believe is sort of a shadow of the Catholic Church but they don’t know it. Frequently when I’m listening to the local Christian radios, they are preaching on what is right now on the Catholic liturgical calendar. People think that the Immaculate Conception is some sort of biblical thing that applies to Jesus. haha. wrong. Look it up. As to what is and is not true, haha again, we can stay up all night saying yes, no, not true, true. Neither of us will convince the other. I’m going to bed.
That is I’m going to bed after I pray to Mary and the entire Communion of Saints including my parents and brother. I’m pretty sure my in laws are still struggling through Purgatory so I will pray for them but not to them. Oh, and I’ll probably find some time to worship and adore my Lord and Savior Jesus Christ. He’ll be the happy one in the middle of the entire bunch....
