I don't see any reason why I should transcribe a video for you, when it's freely available to watch at your leisure. I find the video series insightful when it comes to understanding and combatting bigotry and those that champion it-- and for sure, you may not. I only wanted to bring it to your attention because it directly applies to the discussion, and assuming your end goal is combatting bigotry, you might be interested in knowing that the way you're going about it isn't likely to work.
the video provides context for the conversation. if you're not interested in doing the work in order to participate, fine, but demanding that they transcribe possibly thousands of words just because you refuse to watch the video isn't reasonable.
they have no obligation to do exceed to your entitled demands, and this is not a "profession" but a casual conversation. again, if you refuse to make the effort to do what's required to participate in it, then that is your choice. don't complain when others won't do that work for you.
