Quote from AAAintheBeltway:
It was racist in the same way that any criticism of Obama here is immediately called racist by some idiots in the media. If a liberal had tweeted the same thing, they would have called it a celebration of diversity.
This athlete had supported a political party that the Olympic big shots had no time for. Thus, they lept at the chance to make an example of her.
Calling the party extreme right wing nazi, etc, is also meaningless, since we regularly see mainstream republicans called the same thing here. The fact is the party is legal and has substantial support in Greece.
