And this is another reason why a lot of people don't like the "believe all women" statement. Because dramatic in the moment events and lack of thought lead to impaired memories and actions. Just going "he's a molester" with no concrete proof is the perfect example to fallibility of humans and that original statement. Not to mention it's compounded by the fact that none of the characters seem the grasp the gravity of such a false accusation or even questioned the validity of the claim or looked for proof before immediately labeling him as such. Not to mention, again, some douchebag white knight decides to assault him immediately.
If anyone should be getting chewed out, it's that muscle head who decided to assault someone and every moron who just assumed he was a molester. The girl misunderstanding was more reasonable but even she should be reprimanded, albeit to a lighter degree. This shit gets me almost as heated as that fucking pedophile claim in 3D Kanojo. That one should have been a straight up fucking crime.
