'mass migration' is a descriptive term not a politically loaded term. you say as much yourself when you say that it was immediate. you appear to be avoiding the question as to whether having an opinion on immigration policy is automaticaly racist and whether policy may or may not have had an impact on how the recent windrush issue has arisen (or maybe I am missing your point). or whether this is something that the working class only have the right to comment on. and working/middle class is not binary. anyway, it's late. cheers.
