Why do people get so offended over anything nowadays?

So once I made a list of my 10 favorite movie directors and people got offended because I didn't include black directors or directors like Scorsese or Tarantino

Anthony Mackie 2 years ago critizised Harry Potter for not having black characters

Tim Burton is being accused of being racist for not including too much black actors in his movies

Also people get offended because I rank movies in a certain order

Seriously what the hell? Just because people don't include black people in their movies doesn't mean they're racist. I don't go around paying attention if people are white or black! Also people treat my ranking like if it was a crime!

The reason I love those directors is because of their movies! Their race has nothing to do with it!
