Don't be silly, @MissBeans83
I am sure that almost everyone on this board agrees that racism is a bad thing.
However, when the definition of racism expands to contain nonsense like the OP's post then that is a bad thing.
It is a bad thing because it dilutes the definition of racism. People find themselves accused of it for absolute nonsense or they read that a cry of false racism can lead to a young white man dying in the street.
When this happens they conclude that the definition of racism has become so wide that everyone will be accused of it at some point or other, so it becomes no big deal. They reasonably say, "So what!"
That will eventually lead to people saying "So what!" when the racism is real and serious.
That is why calling every woman and her dog racist is a bad thing.
You are part of that problem.
The more you over react with cries of Nazis and the ilk-to this non incident of the OP-the less seriously you will be taken.
So, it has started to eat its own tail.
That may lead to the definition being narrowed and made reasonable once again and that is why looking for racism everywhere may be a good thing ,as it will reign it in as people care less and less for being called racist for things like general rudeness or reading a copy of Enid Blyton's Noddy.
So, calm down, get with the programme.
You are part of the problem that will eventually lead to a growing number of people no longer caring about being racist whether they are or not.
