Hello CapeCodder;
Yes, I've noticed this for years since the late Harold Camping prophesied the end times dates and end of the world in 2011. Camping was widely known by the Christian community here in the San Francisco Bay Area where my wife and I reside (Daly City, border of SF.) The man owned and operated an FM Christian talk show station, KEAR and was an evangelist.
(Friendly reminder, we don't delve into discussions of End Times or Rapture of any form per our forum rules.)
I don't know how you feel about these many videos but encourage you to stay consistent with the Word, pray as the Holy Spirit leads you to search Biblical topics on "live" internet.
To me, there are thousands of End Time videos floating on YT and other internet sources and are so convoluted. Therefore, I ask the Lord for wisdom and discernment. I'm very careful that I don't hinder the spirit, prophecies, and test everything against the Word of God.
I do enjoy YT as far as listening to good music, a good sermon from anointed ministers, sports highlights and news clips.
God bless you, brother, and thank you for sharing.
