Was Paul Gascoigne consciously racially abusive? Highly doubtful.
As his defence pointed out, Gascoigne is a somewhat unreconstructed individual, I doubt if he would understand the term 'insidiously racist' as the judge put it to him.
But - just because offence is not intended, that is not an excuse for it - by that measure, no-one who ran over a stranger would ever be prosecuted again because no harm was meant.
So Gascoigne has been charged, tried and convicted. There will be those who think is sentence, and indeed even the charge, were overly harsh, there will be others who think justice for the greater good of society has been served. And there will be those, and I seriously suspect Gascoigne is one of them, who will be rather baffled by the whole thing.
Comparing penalties is utterly futile - laws are based on circumstances, charges, evidence, mitigation, and a judge's experienced opinion. There is no 'this was worse than that' - it is a debate cul-de-sac, and best avoided.
