I think your friend was a remarkable man. I have read all the related material about him.
I don't think bringing this all up again serves any purpose. I also don't think trivialising someone's apology by saying it was "buried" helps either. It appears in fact to demean the apology.
An apology should always be accepted in the manner it was given. Having read all of this I would prefer to have seen you saying starting your other thread was a mistake on your part and dropping this subject and admitting we can all be wrong on occasions.
I wasn't aware of this man until now and find his life extremely interesting.
