All good questions.
Hello, Agustarella. I can't answer that one as I am too much of a lightweight ever to get involved in the DM's politics section. I am strictly 'lifestyle'.
My personal view is that I would be beyond delighted if the DM became pro-Remain. It couldn't change anything in itself, but I can only hope that if there's enough pressure from all sides, we could at least end up with a re-referendum. As I say, though, that's just my personal view.
Safari, I've never had anything rejected because it's not in line with the DM's politics (if you mean party politics). I have, though, had to re-write pieces to bring them into line with the house style. I've also had pieces killed at the last minute, just because (eg) something else more topical has suddenly emerged.
Mike, agree re 'truth universally acknowledged' and all similar lines. And I also agree that there's definitely a toxic element to anything to do with women and weight - though that's even more the case with sleb magazines. I think the ones that worry me most are the really insidious comments - the Telegraph, for instance, will always start pieces on actresses/female singers etc with a little paragraph about their size, their hair, and what they're wearing. I find this even more toxic than out-and-out 'look how skinny so-and-so is'.
Troy, I have never in my life submitted a piece to any publication with a single spelling or grammar mistake. Though I have sometimes corrected subs, who have imported mistakes (this goes for all the publications I have worked for, not just the DM).
Whatabout - I couldn't say! I have only ever spoken to him on the phone, and he was very polite to me. Every section has its own editor, so you only ever really have dealings with your 'own' editor, unless there's a good reason to have dealings with anyone else.
