Not everyone is ready for the truth at all times. Sometimes what you said to someone may only resonate years down the road.

I used to feel like I had to get people to agree with the truth just because it's factual. Like maybe if I approach the argument a different way or point out errors in some of the things they are saying, they would have to accept that they were wrong. (because that's how I am)

I had to learn that you can't get people to do things they don't want to do if they aren't ready to do them. Some people are stubborn and will have to find out in their own time.
