Cardiff had a particularly strong BNP contingent in the fan-base, iirc. Don’t know if that’s still the case.
Teams/clubs can provoke different responses. Bielsa teams usually great; horrid fanbase current beneficiaries of Bielsa-ball, as opposed to Athletic Bilbao, whose fans totally deserved his time with them.
For this reason, always felt Mourinho at the Swamp was a perfect match. No cognitive dissonance to overcome, just a shit team, managed by a shit manager, who was employed by a shit club. Likewise Cardiff under Colin. We’re talking physical repulsion.
