As a political writer, I am all too aware that newspapers are not unwilling to publish me when I write in to discuss the ineptitude, expense and corruption of the EU. Nonetheless, it is considerably more difficult to get an evangelical letter published - [although a few do get through] - and almost impossible to get letters into the press which attack the alleged scientific base of evolution.
The more evangelicals write in, the greater the chances of our views being represented. Why not promise yourself to write one letter per week and E Mail it to various newspapers? It can do some good.
Should you choose to do so, please remember the following tips. Do not quote Scripture at readers. Do not pontificate. Do not generally mention either God or Jesus by name. Do not assume that people should accept your opinion because that is what the Christian view happens to be! These are just too easy to attack and will attract atheistic writers like bees around a honeypot who will then get more space than you had! No point in writing, then? - Au contraire.
Use logic and not what others will perceive as being mere opinions.
eg) "If the Christian teaching on sex before marriage had some currency in our nation today, then........... would not be the problem it is."
Go on. Have a go!
