'If certain sections of our community are not prepared to forget Britain's involvement in the slave trade...' Phew ! That rules out the Muslims then. They were , historically, slave traders [ from the same source]
...or the Empire...' Oh dear! They're back in again, 'sleeping with the enemy'.
Plenty of people, and some 'community (or communities)', in America don't forget segregation ( and discriminatory laws, too). They can't, then, be fully integrated and 'are sleeping with the enemy'. I wonder which country they should go to, rather than remaining in the one where they were born.
Strange thing is, they don't get called 'anti-American' if they recall that, complain of it, or criticise the country for allowing or encouraging it. But some people over here are called 'anti-British' for recalling, complaining of, or criticising, this country for allowing or encouraging some conduct in this country's past.
Why is that?
