Just because I tolerate your opinions, doesn't mean that I agree with you. Think about it. I tolerate being cold or hot. It's not what I like or want. I tolerate it.
If I agree with you, I agree. It's when I don't agree with you is when I'm tolerating your views. Just because I don't walk away, or punch you in the face, doesn't mean I agree with you. I'm tolerating you.
