And maybe I read it wrong and you weren't actually sending this letter and that was just a stylistic choice, but my impression was that you had actually sent (or were planning to send) this letter to the people involved, and that's where I say kudos on actually doing something about it instead of just reading about it as most people will do; I just want to try to increase the chances of them responding how we would hope they would respond.
Finally, thank you for the reply and for receiving my comment in the spirit in which it was intended.
As for the whole "proud to be an American" bit, I am just being honest. I feel ashamed that this is where we are in 2015, reprimanding a young man for furthering his education...that kind of behavior starts a very ugly snowballing of worse and worse things to come if it is not corrected.
I did send this message to them. I wonder if they will ever reply. I think that the POTUS invitation speaks volumes about the magnitude of what has happened. Thank you for your feedback. I really do appreciate it :)
