Additionally, why would being kindly EVER serve as a "red flag"? It's obviously not up to "Emily" to decide whether or not "Clint" is truly a "nice guy", unless she is supposed to be some sort of deified Authority on the matter. I should hope that she would be a lady and reciprocate the kindness; it's kids' stuff that hardly requires explanation, L.L.O.L.
Finally, I don't claim to understand the intricacies of feminism, which are surely encyclopedic in length, (as is most rationalization and ideology) but it's hard to imagine that any academic, politician, or clergyperson would ascribe moral credibility to the sorts of teasing we encounter in f*cking Elementary School. Cheers, mate. Keep it Hurley, Dude.
