I feel that if you're expecting your 'whole friend' to be exactly compatible with your opinions, you're not really looking for friends, you're looking for confirmation for your own opinions. I fully expect to disagree with a lot of things my friends say or think, and that there will be arguments. When we do argue, sometimes they change their mind, sometimes I change mine but mostly we agree to disagree. What makes a difference between a friend and a non-friend is that even if we disagree on some fundamental things and a lot of trivial things, our core values more or less align, and both sides respect the other and realize that there is no way you're right about everything. If you are, you don't have friends. You have followers and sycophants.
