By replying with "and?" right from the start when informed that he accidently(?) ruined her shot. It shows a lack of consideration for others.

That is what made him an asshole. Not because he didn't move and not because he sat down. This is why I tried to remove the videos actual events from the discussion. You are super hung up on the fact that it's a vlogger and a random guy but in reality the concept I am getting at is universal and has nothing at all to do with the events of the video.

He is an asshole because he instantly talks down to a random stranger who simply had a semi-reasonable request.

Treat people with a basic level of respect. It's baffling that you are actually arguing against this.

I'm not continuing this discussion, it's pointless. One day you will understand or maybe you won't.
