Now, if you want to argue, as you seem to be, that someone who came to the UK as a 2 year old, 75 years ago, and one who came to the UK as a teenager, 53 years ago- both British for over 50 years, is not to be considered legally or 'socially' entitled to an opinion on things seriously affecting the country, our family and friends, and ourselves- then you are demonstrating massive prejudice, and possibly racism. Because racism is not just about 'race' in fact- and in the case of OH, would actually apply as he is very mixed race and arrived in 1948, at the same time as Windrush (but on another ship, from SA).
I think that is the paragraph which claimed racism that is why it is disputed and, as we can't see one another or know who our relatives are unless someone states their ethnicity and that of their family, it is a spurious claim.
We're not discussing race, ethnicity, nationality, posters are trying to point out how Brexit might have affected them, if at all.
Of course you can have an opinion but so can others, too, but whether it is of any value and whether any of us can change anything at all is a moot point.
Perhaps it would be better to ask posters to list the changes they may have experienced, if any, over the last seven years, positives too, not just concentrate on the negatives.
