Yes, but Edith, surely to God you (general 'you') wouldn't be stupid enough to hold onto that, would you?
So I have a number of CVs and one is from Mohammed and a white British man turns up - I'd be surprised, he wouldn't be what I was expecting, but I wouldn't continue to think of him as a Muslim.
I'm honestly not sure the point that is being made here.
All sorts of people have children. Some are poor and some are overly influenced by current trends and celebrities. Some go for traditional and timeless names.
So do I 'know' those with 'poor' names are going to be stupid?
Well, no, because on a CV you have their qualifications as well 
And then I was named after Ancient Greece so about as middle class or aspiring as you can get (think Adrian Mole's Pandora) but I go by a shortened form of it which sounds like a 'lower class' (darling) name.
One of the poshest families I know had a son named Morgan. Hasn't harmed him - he went to Oxford and is doing a PhD there.
Because let's be clear here, what people mean is 'thick.' People might thick you are from a thick family so you will stay in the dregs because even if you are actually quite bright, no one will give you a chance because of your name.
I don't think that's true. Statistically, social mobility is a bit of a myth and people do tend to stay roughly within the social class. There are loads and loads of Rebecca's and Alexandra's and Amy's from my generation from 'thick' families who have 'stayed poor' (haven't gone to university in other words.) Nothing to do with their name!
If Jaayyde is actually pretty switched on and does well then her qualifications speak for themselves.
