Nigerian is not a race, it doesn’t need to be a race for this to be a racist trope. Reacting to this story with a Nigerian scam email joke is racist. As it is completely irrelevant to the topic being discussed and it is used to dismiss the claims made in the article.
If the Israeli government imposed a fine and then someone on here decided to respond with a joke on how much interest the Israeli’s would make on the fine or whether the fine would be paid in gold coins. That would be racist trope. Whether it happened in the past or not is not important.
It is up to you to remain educated, but I would be careful making Nigerian scam jokes especially around black people. If you want to say racist things, endeavor to do so in private.
Given the terrible (deliberate) grammar mistakes, should we criticise any criticisms for also being elitist?
