Their example is about religious discrimination not racism. Also, people like Muslims don’t abstain from things like pork, alcohol etc because they don’t like it, they’re just not allowed to consume those things by their religion. Muslims can consume pork in emergency food shortages and stuff like that afaik, so I’d imagine you could probably find Muslims that have tried and actually like these things despite not being allowed to consume them.
