Tolerance is about recognising and accommodating the fact that others have different needs, feelings, and/or behaviour.

the UN put it well -

1.4 Consistent with respect for human rights, the practice of tolerance does not mean toleration of social injustice or the abandonment or weakening of one's convictions. It means that one is free to adhere to one's own convictions and accepts that others adhere to theirs. It means accepting the fact that human beings, naturally diverse in their appearance, situation, speech, behaviour and values, have the right to live in peace and to be as they are. It also means that one's views are not to be imposed on others.
