To be perfectly frank with you, I have read many of your postings and have not recognised you as a person of colour. Unless someone expresses their race or colour and I am aware of it, I guess I don't give it much thought.
It seems to me that you are telling people this for some reason...but I can't think of a reason why you should..or should even feel the need to. Why do you need to "publically acknowledge your black racial identity" Only those who know me personally know my colour and race.....I don't mind people knowing but I don't need to declare it publically.
You don't actually state WHY posting on mudcat is emotionally challenging and draining for you and I am not sure that I understand why it should be for you any more than anyone else. It can be draining for us all at times, especially if we are under attack...but I have to say it is usually my own words..or should I say misuse of words which causes attack for me.
Hope you achieve whatever you are trying to with this thread.
Best wishes, Mike.
