Bumper sticker against Native language?

Just this morning I saw the following bumper sticker:

Okay, I'm all for the first part. Literacy has had some negative effects on Native languages, but that's mostly a side-effect of the way literacy has been implemented rather than an inherent problem with literacy itself. But the second part? Thank a soldier that we're reading this in English? Isn't that just about the same as thanking a soldier that we are NOT reading this in a Native language? I guess in some sense it IS ultimately soldiers who are responsible for the demise of Native language in Alaska.
