We should all do this. A more generic template:

Dear MY MP,

As a digitally literate citizen of the 21st century, I'm sure I don’t need to explain why David Cameron and Claire Perry’s attempts to censor the Web are so dangerous.

I’d like to know your thoughts on why this isn’t being debated in parliament; why it seems to go against their own policy after a consultation on the issue, and whether you (as my representative) agree with Mr Cameron’s ideas?

I’m deeply concerned at the scope-creep of these policies. We all oppose obscene images of children and rape. But those are illegal, and filtered, already. Is it true that we will have to opt-in to “extremist” material, and material on “smoking”? Who decides what is “extremist”?

I urge you to oppose this censorship by the back door, and I hope you’ll raise it in parliament, which is the proper place to debate such matters.

Yours sincerely,

MY NAME
