Well I knew I would get some sneers. I wasn't expecting 3 quick ones on the trot. At least Butcher has some humour about it. Funny thing is Butch, that Hitler was linguistically adept, maybe that is your point.
It's not about "educational standards" Red Storm. Nor is it about class. Do I think their grammar, syntax, spelling etc. is below that of the average working class? Almost certainly yes, though their are exceptions. I have done a lot of teaching in my time and class is no special predictor of the ability of an adult to use full stops.
The predliction for caps-locks. The common allergy to nearly any punctuation made up for by an over use of exclamation marks. The hyperbole. The froth. It's funny as fuck. Perhaps laughing at it (as you point out there is a notable FB page dedicated to it, which is also very good from a general anti fascist pov) is a distraction from how horrible it all is. Perhaps it's that which I struggle to fathom - the blind hate, but I also have a small amount of potential sympathy for people so alienated, lost and duped.
Overall though, sympathy and understanding of lower educational attainment or whatever goes out the window when the hate comes in.
The politics of these people make them fair game for humour. People who extol the virtues of England and the English look stupid when they can't even master the basics of the language. Most immigrants I know have a better command of the written word, which again has bugger all to do with class.
