You, in combination with the article, are describing an is/ought situation here.
Displacing aggression---biting another rat---reduces your stress. (This is an is statement.)
Therefore, to reduce your stress, you should bite one of the other rats. (This is an ought statement.)
But biting another rat leads to a stack of bad downstream consequences, which may include things that raise your stress. Therefore, not displacing aggression is the better option; certainly, telling other people to do so is probably not a good idea. Even if you are displacing aggression in a safe manner, by chewing on a piece of wood or yelling at a tree, you train yourself to respond that way to stress and will eventually end up biting an innocent rat.
Oh, sorry, I didn't mean to imply any "ought" here at all. I should've been more explicit. I thought my opening remark of "depressingly enough" was sufficient to note that I was lamenting the "is"ness of the situation, and don't "recommend" it (yikes!).
