Crumlin had a bad name. When I was growing up in the Dublin Corporation housing estate in the 1960s and 1970s, we felt angry about the perception that we were less respectable than anyone else. Reputation mattered – if you gave a Crumlin address on a job application, you probably wouldn’t be called for an interview. The estate featured in the newspapers only in court reports, with judges wondering rhetorically whether anything good ever came out of Crumlin. Some of this rubbed off on some of us – the idea that you came from a place that was no good fed into low expectations: if this was what they said you were, you might as well settle for it.

Over time, this all changed. The stigma could not be sustained in the face of the reality that Crumlin was an ordinary place, full of ordinary families who worked hard, did their best for their kids and got on with living decent lives. And now it’s back, thanks to a single clown. Conor McGregor purports to love Crumlin, to see its people as his people. If he does, he has a funny way of showing it – by smearing the place in the lurid ghetto glitz of the Get Rich or Die Tryin’ culture. Crumlin kids need that allure like the hole in the head that is its ultimate outcome.

Insignificant problem The week before last we had McGregor’s show of contempt for the law, his BMW i8 dramatically pulling in to the car park of Blanchardstown district court, its doors left ostentatiously open to show that he was just popping in for a minute to get rid of the insignificant problem of having been clocked driving at a murderous 158km/h. Last week, we had the Instagram images of McGregor throwing £20 notes from a large wad at the twerking backsides of scantily-clad lapdancers, while his pals, described in the tabloids as “Crumlin criminals”, made lewd gestures. It is all part of the gangsta image that McGregor seems determined to foist on his native place.

This is a disgusting kind of life, but McGregor makes it both desirable and apparently attainable by branding himself as just another kid from the estate. He isn’t. McGregor can live it because he has phenomenal talents as a fighter and self-promoter. The Crumlin kids who look up to him can live it only if they carve their way to the top of the drug-dealing business. For the vast majority of them, there is just one viable route to driving a BMW i8 and throwing wads of cash at lapdancers, to the private plane and the magnums of champagne. And for the vast majority of those who take that route, it will lead to addiction, squalor, chaos and misery. They are infinitely more likely to die tryin’ than to get rich.

I don’t think for a moment McGregor would wish this on any of them, but the reality is that his publicity machine has redefined Crumlin as the white gangsta capital of the western world. It is very easy to laugh at the ludicrous ESPN magazine profile of McGregor that appeared in August as part of the carnival barking for his Floyd Mayweather fight. But it is headlined “Crossing Crumlin Road” and Crumlin is name-checked 27 times, almost every one of them in the context of criminality, violence and drug-dealing. Even Brendan Behan’s satiric description of Crumlin as a place where they “eat their young” – a mockery of the ignorant stereotypes – is dragged out and used as if it were unironic social realism. The profile revels in the stigma: “Proper Dublin recoils from his type: the Crumlin hood rat.”

Racist and homophobic In the McGregor myth, even a compliment to Crumlin kids turns sour. Thus, in John Kavanagh’s book about coaching McGregor, Win or Learn, the star’s racist and homophobic trash talking is all Crumlin’s fault: “I think you can trace it back to Crumlin, where there is real wit and edge to the way young lads talk.” So using the slave slur “boy” when addressing a black opponent, or repeatedly using the word “faggot” is the Crumlin version of wit.
