It sounds like you feel he might be trying to change your views by sending you these videos? That to me isn’t a very respectful thing to do. Friends should respect each other’s different views, as long as there’s no harmful effects from them of course.

I have a good friend who is religious and I’m not, it’s never been an issue for us. She talks about going to church but in a matter of fact way. She doesn’t send me messages to try to change or challenge my perspective and I don’t criticise or challenge her beliefs either. I wouldn’t like the situation you describe, it doesn’t sound respectful to me.
