In practice, all that accomplishes is everyone tries to cast their opponents as "intolerant" so they may be censored. And "intolerant" is such a broad term, it can be applied to nearly everything, and abuse is guaranteed.

Accusing a whole group of racism and guilt based on skin color? Intolerant.

Want to close the borders? That's intolerant of those who want to enter.

Drawing disrespectful cartoons you know will cause backlash and division? Intolerant.

Boycotting a country or business because they endorse said cartoons? Also intolerant.
