It’s undeniable that some immigrants to the West hold those values, which are incomplete with our own.
Two centuries ago, that could have been written in reverse ... it was British emigrants that held values that were incompatible with those of the colonial outpost. Which Britain then proceeded to piss all over and impose "decent British values". Whilst relieving the population of any burdensome wealth they may have accrued.
Now two wrongs don't make a right, but you can see why an immigrant to the UK might think what's sauce for the goose, etc etc ....
