I can't say what it would have been like at primary school, but I do think that you are giving changing attitudes not enough credit.
I do recognise that the child could have a rough time, but as long as the school supports him, and tackles any bullying that does occur promptly, then it might not be so bad as you imagine.
Alternatively, as you can also get bullied for wearing glasses, liking mayonnaise with chips, wearing Postman Pat leggings, and pretty much anything else under the Sun... it's almost impossible to avoid bullying anyway. So you may as well just be yourself.
