It's unfortunate to see so many learners specifically requesting to learn with native English speaking teachers. It's not true of all learners, but a lot of them seem to have this misguided preference. Although, I wouldn't advertise myself as a NEST because it's just not important, I rarely call this out because I don't want to have a debate with learners before I've even started teaching them.
So, my question for you guys is what responsibility should we bear, whatever your first language is, for arguing against this learner preference?
