I am a member of an interest group which I dip in and out of - events happen throughout the year, online, long-running, one off etc. There is an element of being in a role/creating a character. There are people who are much more immersed in this full-time/amount of equipment etc than I am.
A person posted in an online group that they have been working around practising using a particular accent for their next event - pronciation, certain sounds etc. They say that other people in the group are fine with it. They are not intending to be racist etc. They say that other people do Nordic/Turkish accents etc and it helps with realism and is not a 'comedic' thing.
The language/dialect/accent is from a country with a black majority population with a colonial past. If it's relevant, the person has said they themselves are not a native English speaker and I don't know their background beyond this post.
It doesn't feel right to me, and knowing this is apparently accepted would make me feel uncomfortable attending an event run by the people who are organising it. I will accept being told I am wrong or overthinking it.
