Today, some people will agree with you and some people won't. And you'll just need to accept those who don't see things the way you do. They're not trying to dismiss you. They're just being themselves. You can't waste your energy picking fights with people about things you can't change, namely, the way they think. If you butt heads with someone, just move on to other people and other things. Agree to disagree and save your strength for things you can actually change.
