"She is quite clearly saying in effect that people in authority should not associate with Pakistani people at all, "
No she isn't. Don't be so bloody ridiculous.
Simon Danczuk raised a Pakistani flag over Rochdale

for reasons unclear.
Pakistanis in Rochdale, for reasons unclear, were aided and abetted by the police & authorities to abuse and rape children for many years. In the past, the likes of Nick Griffin were prosecuted for saying that Pakistanis in places like Rochdale were raping and abusing children. Even though it was true. And the abuse was ignored for 'community cohesion'.
Clearly a British MP raising a Pakistani flag in a divided city troubled by abuse by Pakistani men is not conducive to community cohesion from people who are NOT Pakistanis. But that doesn't seem to concern Mr. Danczuk.
You would not, for example, have gone to Lockerbie, as the local MP, after the Pan Am bombing, and raised a Libyan flag. Or gone to Guildford, Warrington, the Baltic Exchange, etc. and raised a Tricolore.
You would of course serve any of your Libyan or Irish constituents in normal constituency matters, but that does not extend to erecting foreign flags over British cities when sensitivities could not be more obvious.
It is nothing to do with racial hatred, it is understanding that community cohesion works BOTH ways.
