The most common useless phrases all start with something like, "everyone thinks..." or "i know a lot of people who say..." or "a bunch of people are..."
In the church, or in the office, or the school, or within the political party, or or any other place you can imagine both physical and virtual these phrases are completely unhelpful and often toxic.
I can almost guarantee you that the person(s) using these phrases is wrong. They haven't taken the time to get a lot of feedback or specific input. They haven't asked important questions. They often don't even care about logic. They're being driven by emotion, responding to their small circle of friends and trying to sound knowledgeable by making absolute statements.
Don't fall for it. Don't lead or manage that way. Help your people move past the fear of what "everyone thinks" and get to the heart of the issue.
