I think the silly 'abbreviation' to FARTS by some people is neither here nor there: it's a contrivance rather than abbreviation (which would more commonly be 'FAE') by people who clearly want to find fault.
That's a distraction to the main points here.

I actually support the move towards 'England' rather than 'English' in the name change. There's a nuance here: it's a subtle nuance but it's an important one. 'England' foregrounds physical geography in a way that 'English' does not. Remember that this is a branding exercise - the name of an organisation does not have to sum up everything about it (eg Ceoltas, which in isolation doesn't tell you anything about the function of that organisation).

I don't think EFDSS is proposing to replace every instance of the word 'English' with 'of England': just in the name.
