Toleration is the belief that one should not interfere with a thing of which one disproves.
Toleration does not mean that you allow people to do things because you agree with it.
It is a moral principle that you will not try to force your opinion through for example government, your website or app to stop the things you disapprove of.
People should be allowed to say things of which we strongly disapprove. We are tolerating things even though we dislike and disprove it.
