What to Write in a Letter Opposing the Ban?

I have been reading a few posts on HR 669, and I am ready to write my letter on why I am against this ban. However, I am at a lose, I am unsure about what to say exactly and how I should word it. So I was hoping that some of yall who have already written yours could share some inspiration on what exactly should one say.

The bulleten put out by USARK has an okay sample letter (that bulleten has been quoted in full ere a couple places) use that as a template and then just flesh out other things you feel you need to say

Just remember, above all, do not be offensive or rude. The instant you do that is the instant you lose an audience.
