Well it is the same thing.
I'm not a pro-gun at all. But this is a political move as an after effect of the school shootings, pushed by a left agenda for banning guns (which on a personal level I agree btw).
The issue is that you have a private company taking a political position and therefore forbidding specific videos based on that position.
This is something we saw in the past on other political subjects. They are abusing their power as platform as they know they are the de-facto platform used for video. It is about freedom of speech.
How would you feel if they suddenly decided to remove videos about evolution and darwinism? Or videos about abortion rights ? (this will never happen as youtube leans super left, but it gives you an idea how the other side sees it)
