In answer to your question. They are SUPPOSED to.
As to the letter writing campaign, my wife mentioned it this morning and what I found interesting is how we are supposed to remain neutral as to governmental affairs but it's okay if it's something like this.
The other thing is that it might backfire. Remember the letters sent to Hitler back in the day. History showed it made things worse.
The answer I gave my wife was "it's only stuff". That's what they are wanting to protect is their property. At least that's what it seems to me.
