Is that something you just came up with? Because the courts have been using the "reasonable person" standard for years.
It effectively and justifiably dismisses the frivolous, ridiculous, and overblown fearmongering that's inherent in passionate debate, as we've seen with this issue.
Anytime one begins an argument with the phrase, "Most reasonable people..." he is arguing that anyone who doesn't agree with him is unreasonable and therefore the counterargument has no merit apriori.
The use of the phrase is what galls me, since it is used smugly by mostly people who have no real argument nor interest in true debate.
