I have read Moore's works - most are on my web site.
My miss spellings are (a) my poor typing skills (b) haste to post something in gaps between doing other work (c) a computer that is rather slower than I prefer (letters tend to go missing even though I have think I have typed them).
I did not accuse the Manx of being ignorant (although illiteracy was quite high there was good education available for those that could afford it though Hinton Bird in his excellent survey states that the initial rungs on the educational ladder were generally missing due to penny-pinching attitudes and lack of decision) nor dis-spirited - the various letters extant generally give impression of sadness at having to move (and the waves of emigration tie neatly with economic trends) acknowledgement that things are not always easy where they are but that they are generally preferable to affairs back on the Island. I refer you to my papers on Manx emigration also on website.
The rules regarding travel to England were virtually non-enforceable - Manx being treated as subjects of English crown (the Lord of Man being a vassal of the English Crown) they could move to England, own property etc (eg Philip Christian in London mid 17th C - see also Gill's comments on Manks names in early Lancahire/Cheshire records)
I dont disagree with you re language - my point was to try to dispel any myths that I frequently see (eg that Manx language was outlawed) - it was a choice by the people, maybe not conscious but by the people nevertheless - they did not teach it to their children and used English - Moore for example learnt Manx as an antiquarian but did not teach it to his children!. BTW there is virtually NO norse in Manx - this is surprising given the supposed Norse control of the Island for 2 or more centuries. The Island had been a mixing ground of peoples for a long period (BTW there is virtually no indication of Roman vists and would very much appreciate any evidence to the contrary!) - not suprising as the Irish sea is better viewed as the motorway of communication for several millenia with the Island a well placed service station midway in any journey
