Diversity is good, but forced diversity is not. There is also the fact, that some creators make bad charcters and instead of owning it to their mistakes, they call their fans racist and stuff.
Make a great story with decent characters and nobody is going to care, if they are white, black, green or a f*cking Klingon. If the creators were doing their job properly instead of focusing on B.S. politics, then we wouldn't have this problem in the first place.
Writer writes, actor acts and etc. Is that so hard to understand?
I don't disagree with your points but I don't believe that is what the video shows with the guy who has the YouTube channel is a little extreme.
Maybe it's just me, but this looks like they edited this on purpose to make the guy look bad. They spent the whole video just mocking the guy. I wouldn't be surprised, if some guy with a camera shoved up shouting: " It's just a prank, brah!"
