"Stupidity" of "my arguments"? This argument "WP:YOUTUBE" (which is indeed about external links, but also mentions how YT is actually not "blanket banned" on Wikipedia, but should be always checked for not breaking copyrights), along with was not even originally brought by me to this discussion, but by dearest Mr. Stalker Mine in one of the links at the top (but I won't object regarding "stupidity" of that). Anyway: there's nothing that makes these particular sources un-reliable just because of the platform used.
