HOW CAN YOU POLITELY TELL YOUR MP THAT THEY ARE AN UTTER UTTER MORON?

It's bang-your-head-against-the-wall time.

I just wrote to my MP about the Middle East, North Africa, 9/11, General Wesley Clark, bin Laden, A Clean Break, PNAC, etc. All the stuff I write about here. Their reply was:
1. al Qaeda did 9/11 all on its own;
2. that we should love Israel;
3. that we should love Saudi Arabia even more than we should love Israel;
4. that the British government is doing a fine job over Syria.

Apparently, it's all about something called 'national security'.

I believe that my MP is an utter utter moron.

How can I politely tell my MP this?

I was thinking along the lines of...

Dear ...MP

Thank you for your not so prompt reply, but I respectfully disagree with your utter utter moronic belief that:
1. al Qaeda did 9/11 all on its own;
2. that we should love Israel;
3. that we should love Saudi Arabia even more than we should love Israel;
4. that the British government is doing a fine job over Syria.

Yours Truly

Whadda yer fink?

Succinct?

Polite?

Or just abandon this and try something else?
