Ummmm - YouTube is a great resource and free lectures are available to all.
It is convenient to hear experts in various fields provide views that otherwise would be beyond our reach, certainly mine.
To compare it to a religion is either a weak attempt at humour, or a totally unfounded grasp of its content or use.
I use it to not only get information from Christian apologists and experts on theology, but also to listen to atheist viewpoints and evolutionists.
Is any of that a cause for criticism or mockery?
