Jehovah's Witnesses; I Know That You Use These?

Jehovah's Witnesses; I know that you use these scriptures (Matthew 24:41-42, Matthew 25:13, Mark 13:32-37) as the excuse/justification for judgment errors on your predictions but have you ever thought about this?….. We are talking about with reference to "keeping on the watch" as mentioned in scripture and using that as the go ahead for these wild predictions. So why does God give such authority to blunders upon blunders based on a "keeping on the watch" scripture?

I would have thought the "keeping on the watch" scriptures would be there as like words, motivating individuals to never give up looking for true signs and the end to happen; not as a free kick to say whatever you like on how and when it was going to happen.

Why should your governing body have the permission to make wild predictions, and advocate truth in wild predictions as to make out like this how and the time God is going to make things occur?

So when did all black/African America JW's turn white as the Watch Tower Society predicted ? When did jc return in the physical in 1970' and 1980's ? How do you or the WTS know that jc returned in invisibly in 1914 ? What proof do you have ? Why is it against WTS to read old Watch Tower publications ?
