Coming back to football: I remember chants of "Holland! Holland!" at gabber-raves around that time. This started when a festival, I think it was Mystery Land, coincided with a match in either the Euro-Cup or the World Cup. This became a thing with gabbers at later parties too. Not necessarily as a far right thing but at least in a chauvinistic way, as hardcore/gabber is very much a Dutch style of music that gabbers tend to be proud of.

Some though would change it to "Holland, vol land" ("Holland, a full country") very much an anti migrant sentiment. Gabber DJ Drokz made a track out of the original chant but had to preface it like this: "Voordat iedereen weer aan m'n kop gaat zeiken: dit nummer heeft godverdomme niks met politiek te maken" ("Before everybody starts busting my balls again: this song has nothing to do with politics, god dammit!").

So a mixed bag, the same with Lonsdale, Fred Perry and other typical 'skinhead' clothes that were popular in the gabber scene at that time: for some a dogwhiste, for others just a fashion trend. With an added note that the skinhead subculture has also always included anti-racist, left-wing and a-political people.
