Mab6q, you bring up an excellent question!
This goes to the heart of what our task on a principle support question is. A typical stem reads:
"Which one of the following principles, if valid, most helps to justify the reasoning above?"
We want the answer that most justifies the reasoning. If it goes way, way too far, who cares?! All we care about is how much it will justify the conclusion. The more the better!
Take a simplified example:
Premise: Jack is wearing a blue shirt.
Conclusion: Jack is going dancing.
Which of these principles would justify that?
1) If Jack wears a blue shirt, he must go dancing.
2) If Jack wears anything blue, he must go dancing.
3) Anyone who wears a blue shirt must go dancing.
4) Anyone who wears anything blue, ever, in any way, must then go dancing.
All of these justify that conclusion! Some go farther than they need to, but they all get the job done.
Now, if this started to smell a bit like a Sufficient Assumption, you'd be spot on. Principles often dress like Sufficient Assumptions (though not always). And just like Sufficient Assumptions, they can be stronger than they need to be.
In this question, since character attacks are certainly in the category of 'debating techniques that do not confront every argument', this principle will absolutely help to justify the conclusion.
Please let me know if that completely answered your question!
