Skin colour shouldn't be a factor when offering to help the poor and disadvantaged.

If I were to drop off 100 pounds worth of food to a food bank but I said please only give this food to white families do you think that should be acceptable?

So Stormzy's offer should also have been turned down then?

If you think about cultures theres afro americans, cubans, jamaicans, south africans, asians but for caucasions there is only white..
Why?
I dont know but like ogdenz pointed out, it shouldnt matter because disadvantaged isnt color specific however, some cultures are obviously worse off than others

As Sir Bryan himself has said if Stormzy can do the same for poor black kids, why can't I do the same for poor white kids?

Working class white boys seem to be one of the worse

In my opinion yes. Sadly that means nobody would benefit but there ya go. There should have been no proviso on the offer to help.

Its overly PC for the sake of being pc

He should be able to help out whoever he chooses..everyone's become so hyper sensitive in regards to race and gender that they've become wary of offending any demographic..
Before social media none of it mattered

Shouldnt say it didnt matter..
It was low key

Would have agreed with that until recently. Now I think their money, their choice and it's helping poor kids out.

Think any demographic in society will feel as though they are being mistreated and not given a fair chance, if wasn't black children, it would be gays or trangenders, instead of focusing on the positive aspects of what is being done like giving a child an opportunity to receive a decent education..

Without having bothered to check and with absolutely no intention of doing so, perhaps Stormzy didn't actually attach any ethnic selection criteria to the money he donated, which the other chap seems to have done.

Nope stormzy set it up for black kids only. BBC news from August 2018

He can help poor white kids, he just can't help only poor white kids. He could at least consider helping other poor kids as well, be they black or otherwise.

He hasnt offered to sponsor white kids but offered a bursary that could only be spent on white kids. If he actually sponsored the white kids it wouldnt be a problem and thats actually what Stormzy did do isnt it?

Stormzy specified his money could only be used for black kids, so it is the same thing

Well, the rules should be the same for everyone, so i'm guessing there must be something in the way in which Stormzy is donating his money, that allows him to do it but not the other guy.

Possibly, If Stormzy is awarding scholarships through a charitable foundation he has set up specifially to help black kids then that could be allowed somehow but because the other chap is giving money to the school directly, the school then can't accept the money under the condition that it must only give it to white kids. If the charity is selecting who they are helping, not the school.

He actually sponsored those kids.

So in this case, my guess was correct.
