So, short people and medium height people can have their own views.... but what about tall people? Who speaks for them?

Tall people are not entitled to have any views of their own LOL!!!!

On a (slightly) more serious note:
Tolerance means you are free to agree with politically correct views or shut up.

“When I use a word,” Humpty Dumpty said, in rather a scornful tone,
“it means just what I choose it to mean—neither more nor less.”
“The question is,” said Alice, “whether you can make words mean so many different things.”

“The question is,” said Humpty Dumpty, “which is to be master—that's all.”

Under the current rules, "tolerance" means you must tolerate bad behavior from whatever group has special privileges at the moment.
Tolerance does not mean tolerating religion or free speech or any such nonsense.

Mr Dumpty summarized it nicely:
“which is to be master—that's all.”

Well said!
