Not strictly speaking, but if they say:

"I found it neat these non-predictive artists were mainly metal. Perhaps the genre that can finally bring this divided country together or break the lock on the two party system."

then it's a small bit of inference to think that they are suggesting metal fans are more likely to go for something other than the two incumbent parties.

Anyway, I'm generalizing a bit here. It's not always necessary to reply only to the conclusions than the authors of an article explicitly drew.
