Are there racism in the maritime world?:
The answer is obviously YES, but it is not only one race that suffer from this.
As most seafarers have experienced, racism exists in many countries and against Black, Brown, Yellow, Red, but also against Whites, (to stick in the popular colour code for different races) based on their perceived skin colour.
There are also “racism” within the same “colour group”, based on nationality, religion, or even degree of “blackness”.
I remember a “black” American Camp boss on a rig in West Africa who had to be replaced because the local catering crews did not want to take orders from him. (OK, he had a bit of an “attitude” himself)
