I have a good memory , I remember generally what other posters have said over certain topics and during the black lives matter the aforementioned poster was vociferous in his criticism of the protestors and the movement . He then informed me that he was mixed race but my view was that he was entitled to his view even though I didn't agree with him . I maintain that racism affects everyone , whatever their colour and whether you live in a multi racial city or not or whether you are black or not you are still able , with a clear conscience, to challenge it . In regards to this case we don't know if racism took a part but I sincerely hope it didn't.
