What a wonderfully wise post, Preeti! I do know some editors who rework a writer's post so much it sounds like they wrote it, not the writer. Fortunately I have not had to deal with rude editors so far. I am sorry you had to go through those two experiences--it is just not the way.
I agree with you that Dr Mehmet is a great example of courtesy and kindness. Thanks for the valuable takeaways!
