Tolerate seems to be primarily a word of manipulation.

Being asked to tolerate something implies that it comes at a cost to you.

The person asking you to tolerate it is asking you to pay a cost. Almost always, they are okay with this cost, or it is not a cost to them.

Ex:

  • Parent, trying to work, asking you to tolerate your sibling being obnoxious
  • Tolerating something new in your town. New people. New corporation. Etc.

The parent is asking you to "tolerate" the sibling, so that they don't have to get involved. They are asking you to suck up (pay a cost) of something you dislike, for their benefit.

The should is what does it. It vaguely implies that doing so is somehow good for you. If it wasn't good for you, why should you do it after all?

Worse still, tolerance is often couched in manipulative moral overtones:

"You're a bad person if you won't tolerate what I want" is a common implication.

Tolerance is frequently a sneaky way of trying to evade responsibility and dodge the fact that they want you to pay their costs for them.

In healthy, reciprocal interaction at a minimum they should be upfront about this:

"I know I'm asking you to bear this burden, will you do it for me?"

Even better is if they are assuming your costs. Offering to compensate you in some way for bearing that burden.

Or if it's a potential risk (company building a new waste plant), being willing to forebear that cost if it turns out to impose on you.

Just another of the many, many, many ways we subtly lie to each other.
