Disclaimer:
If some parts of this video look familiar to a few of you, that's because they were elements of a previous video that I took down.
I'm striving to do my very best in explaining everything in these videos, but in the few cases where I either don't explain myself well enough, am vague, or in some cases don't back up my claims with enough sources, I will remake the video so that it will make more sense.

If I happened to have taken down your favorite video, sit tight, chances are I'm in the middle of remaking it.

Thank you for your patience.
I'm still new at this!
