There is little I can do for blindness, or probably better-put: willful ignorance. If the screen-shot isn't enough for you then there is little I can give you that will convince you. So my request to you is to stop posting your lack of anything useful which does no good in answering the question. I would rather no longer waste your time or mine since very little meaningful, factual information has been offered. A picture depicting the requested permission in front of the Youtube logo on a Samsung tablet will surely convince an intelligent individual they may need to look into the subject. Your contribution would hardly waylay anyone's fears though so how about move on to a topic that you can do some good? Let's face it, you have ignored any questions I have put to you directly as though they have been rhetorical. This I surmise (which if you had the ability to answer would not have to be) is due to your lack of real knowledge on the subject. I have directly addressed those areas you have put back on me to the best of my ability yet you continue to engage in sophomoric attacks that are as transparent as your know-how on this subject so please do me the favor of forgetting my or this question's existence; I would be forever in your debt and appreciate any absence of a permanent variety to a greater extent than I can possibly put into words.
