No, indoctrination comes from Teachers, Science books & TV programming ( literally )
You haven't answered my post #3,630 which was in answer to your own question.
You haven't answered my post #3.634, you just wrote "I give up with you guys" - which you clearly haven't.
You haven't answered my post #3,637 where I've explained the reasons we can't trust anything you say.
Seems to me that you're avoiding them because you have no answers. (No one's produced a YouTube video about it.)
You have written the same things over and over again - eg "truth will out", "anything hidden will be revealed" (the shape of the earth is only hidden for those who don't want to see) and "you'll find out one day". You have failed to explain what difference the shape of the earth makes to our salvation, Christian life, faith and future destiny - either because you can't or because you don't want to admit that it makes no difference at all.
That's indoctrination. You are not responding to posts, considering what we write, asking questions and then responding with more questions, thought out arguments or to say either, "no, you're wrong because of ........." or "I hadn't thought of that; you could be right." Any scientific writings, experiments, studies or eye witness accounts are all brushed aside with "fake" "lies."
At the same time, you expect us to believe your "arguments", interviews and testimonies in favour of a flat earth - sorry, circular, 40,000 foot deep earth.
I think you'd be quite happy if, one day, God condemned the lot of us for not believing his earth was a certain shape - or at least denied us a few eternal blessings.
That will, and can, never happen - read that carefully and write 200 lines.
