It’s often a word that is used in place of acceptance, as if it means the same thing when in reality I would argue that it means the opposite.

To tolerate something or someone is to put up with their existence, this comes with a general idea that you do not like or support their existence, but you’ll just deal with it because you have to.

To accept something or someone is to understand and support its right to exist. You want that person in the world.

See how the words are different, very different I believe. They definitely shouldn’t be used to interchangeably.
