I argue that insults are only fallacious reasoning if you don't have good reasons to back up the insults.

If someone screws you over, you lay out the reasoning for why you're angry at them and then you insult them. The insults are not the argument. They are the conclusion of the argument.

Once again if you see an insult, conclude someone is being histrionic, and refuse to see their actual sound arguments, then you are making the fallacy fallacy, and throwing out the baby with the bathwater.

You are also making an ad hominem against the author - arguing against the personal credibility rather than the credibility of the actual argument. That specific kind of ad hominem is called tone policing.
