Don’t waste time concerning yourself with the choices of others unless they affect the outcome of your own decisions. If you have no stake in the issue beyond your own opinion, opponents are far less likely to hear you. It’s not your problem, it’s theirs. By interfering, you make it your problem and cause undue stress for you and others. If you feel you do have stake in the issue, make sure your opponents understand what’s on the line for you so that you can increase your relevance in the matter. Don’t go to bat without something to swing or a game to lose. Otherwise, you’re just noise.
