Your boss is always right
Like it or not but your boss is always right. Right in the sense that either you have to find a way to “agree” to your boss opinions or you have to find another boss. The reason is that if you are to contribute building a great business culture, you and your boss must have a "one voice", i.e. a common way of looking at things and a common direction for moving forward. So you either find a way to agree with your boss, which may mean that you influence your boss to draw his opinion closer to yours, or find another boss.
