Don't you think that there are some things that need to be left unsaid?
Society has ingrained in us that we need to be independent, speak out, voice our thoughts, all to the point that we feel the need to say things that, in reality, never needed to be said. Stupid things, offensive things, pointless things, damaging things, rude things.
If what you have to say is insightful, uplifting, kind, thought-provoking, or even neutral, then it is acceptable to say it.
People don't know when to keep their mouths shut these days.
