Its humor dude.
1. Its irony at its finest since this campaign is about problems white people face, therefore it is an actual white people problem
2. There is a certain humorous cultural implication and coloquialism (not that its real, but its fun to poke fun at these sorts of cultural silly things)
3. Its pointing out that this supposed problem mentioned in the OP is not a big enough problem to care about. So its pointing out people's silly whining.
4. Its just a funny website (and yes I am white as well, but I can laugh at myself even though its an obvious stereotype)
I hate having to explain jokes.
Try this one.
