I note that the Profile of BostonMike shows the sole post this member contributed was on 13th October 2021. I think the opinion is likely to have been based on experience in the USA rather than what is the case in this UK based forum.
Like many here, I just look at recent conversations, so if I have commented on a post from a verboten section this was unintentional.
As regards the comment by VacuumPumps/Re-establishing Sex Life, it is not clear to me whether the statement that 'Apart from myself, I have never seen a single post from a black or Asian background, as far as I can tell......' relates to a restricted section post or to the general sections of the forum. In any event, how do you know that some of those posting were not black or Asian? There is no requirement to state your colour and most people in multicultural UK would not necessarily state it.
These special groups were set up as a trial in early 2016, so it would be interesting to learn how successful the Charity judge them to have been.
