There is a great difference between toleration and acceptance. We are told that we must learn to tolerate values different from our own as though they were as "good" as our own. That means acceptance. Common sense declares this cannot be if you are to hold to any belief with genuine value.
The secret to getting along with others is NOT to accept the beliefs of others to be as valid as your own. The secret IS to separate the belief from the believer. We can accept civil relationships with others who do not agree with us. In fact, it is necessary in everyday life to do so. So, we can discern the beliefs of (not reject or "judge") another person. That is the original meaning of "tolerate".
However, Today's social and political leaders have changed that connotation of tolerance to mean that we should accept the deepest beliefs foreign to our faith to be as true as our own. Does that mean we should accept athiesm as having the same value as faith in Jesus Christ? Today's "politically correct" would say, "Yes." But, for us to accept atheism to be as valuable as faith in Jesus Christ is to destroy the value of a person's faith in Jesus Christ.
We can find a parallel idea in scripture. There is a faithful saying that we can separate the sin from the sinner. We can reject the sin, as God rejects our sin. But we can love the sinner, as Christ has loved us. That is NOT to say that we should accept criminal or morally depraved behavior, which is clearly what the Bible would call "sin". But, we can discern what others think and feel and how they act without condemning them as beneath us. That would be to "judge". We must discern without such judgement.
So, we must discern the difference in value placed upon faith in Christ versus faith in self or human philosophy without condemning others for so doing. We need to cooperate with others of different beliefs as they should cooperate with us.
Toleration of belief should not mean the same as acceptance of others' beliefs. Toleration allows us to keep our beliefs in tact while cooperating with others. Acceptance of others beliefs to be as valid as our own means to surrender the value we place on our beliefs that they are true.
