don't knock anyone
I agree with you, but would suggest a letter to the 'Editor' and another to the Mirror's writer giving your views and comments on the subject. All you will lose, worst case, is some time and the postage on two or three letters. Also, print your return address on the envelops the way it is done in the USA. Also use two different types of envelops then both will be read, possibly by different people. Last thing, if not too inconvenient, post them from different post offices. In a short period of time you should get at least one reply. Open with a knife to make the opening neat and tidy. Start a file with a copy of what you sent (with the date) and the reply. NO MATTER what the reply is, reply back with a thank you, and maybe add another short comment. Again, copy and keep that as well. If no reply's or comments, write to another newspaper. Be 100% on spelling of the reporters name and what you write. DON'T write a bloody book, just enough to catch someone's interest. No one is perfect, so don't take the piss, or be political.
Last thing, get a simple account on SKYPE before you write to the paper(s) it's what every one I deal with use, as it is always read before email is even looked at. Also, much less unsolicited crap comes that way.
Good Luck!
