This can happen in church too. Have you ever heard: "Some people have told me they don't like the use of PowerPoint"? The 'some people' tactic is usually just a way to make the critique anonymous. The criticizer is basically a troll. They are inciting an argument, complaining for the sake of complaining.
Sometimes, you just need to disengage. Ignore. You can never win a flame war. Ever. Some people just argue and complain. Sometimes you just need to ignore and move on. You can't keep everyone happy. Don't try.
