If you imply that teachers on visa are somehow inferior or worse then citizen teachers (non-existent btw since noone is volunteering for Alaska gig), you are either being terribly misinformed or just bigoted.
I find it harder to learn if I have to decipher the words not the content. This is true for lots of different accents. This is a common experience for those not overindexing on ethnonarcissism.
Alaskan school teachers are paid below Alaskan median wage. If you support importing workforce to be fill less-than-median-paying roles you haven't thought about it very well (chances are you never will).
>racist bigoted
These are not magic words that somehow make your argument sound. Delegating bringing up children to underpaid workers from foreign cultures, desperate enough to consider this deal an improvement, cannot end well.
