"Strange " English language.. [170]
Manx
We're talking about Manx not Manx. (Though in fact a lot of Manx are in fact Mancs and some Mancs are certainly Manx however that's another story and not a linguistic one).
Mancs is probably short for Manchester
Mancs is short for Mancunians, so close.
75% of the UK population
95% where I am however it's hard to say why that would matter. There are a dozen other threads for racists to whinge on.
The UK has been a class-based society for millennia
So fat cherry thinks that the U.K. has existed for 'millennia'. Wow, and there was the rest of us thinking it was created in two stages, in 1707 and 1801.
And social socioeconomic status ('class' is a meaningless word) evolved in the British Isles slowly and in a state of constant flux. The same in Poland and in the US. Outsiders however put too much emphasis on it, and especially on the relationship between socioeconomic status and accent/language.
