Here is a gentle lesson:-
Which is correct? What would you normally say?
Us are left looking like wankers. OR
We are left looking like wankers.
I think you would use the sentence which begins with 'We'.
Therefore, when you put in 'dyslexics' or 'shopkeepers' or 'farmers' still stay with that 'We', as in 'We dyslexics are left looking like wankers.' and 'We shopkeepers are left looking like wankers.' and 'We farmers are left looking like wankers.'
HOWEVER, IF we become the object of the sentence, things change, as in 'Spelling is difficult for us (dyslexics).' and
' The wet summer has been disastrous for us (farmers).' and
'The new currency has made life very difficult for us (shopkeepers).'
Yes, a farmer did once send me an e-mail which started with 'Us farmers' when he should have said 'We farmers' , but I tried not to hold it against him too badly.
Now, I've lost a lot of time typing this digression and I must hurry to the kitchen and make tea. I must be careful though, because I have a loose shoe, and I don't want to trip and lose my balance.
