I think people should be able to publish whatever they'd like. Honestly, I don't fully follow Fiske's argument. There are too many undefined phrases and an explicit unwillingness to use any examples.

I'd believe many engage in ad hominem arguments and abuse. I'd also believe that many engage in arguments of authority. I'd even believe that possibly most people who call themselves scientists make those arguments from time to time.

The thing about ad hominem and arguments from authority is that they are extremely easy to defeat. One simply needs to point out what is happening and continue going.
