I think a mail page is for opinion and controversy... they often publish negative responses in that section (I read People and US Weekly regularly)... The more outrageous the response that is printed.. the better the reaction.
I would assume that if letters like yours are pouring in, then the editor is getting a pat on his or her back for doing his or her job...
My guess is that in reality they dont really care what is in the letters that come in... only that the letters come in.
Gossip and controversy is what we readers of tabloids want-- dangit!
