I have been reveringrevered her for many years, because of the depth of her lifetime achievement since many years.

Revere is is not something typically expressed in continuous tense.

He called her runt and said she had nothing to say and I told him to stop being rude and accept her as she is.

This is not at all the context in which this word would be used. Examples of better usage include:
“The tiny black cat was the runt of the litter.”
“That big bully picked on him, because he was the runt of the class.”
“When I was little I was a runt, but I filled out as a teenager.”

It has to do with physical size and weakness.
