what does it meen????

The lunatic fringe is that section of society which thinks and acts in extreme or irrational ways.

To throw one's hat in the ring means to join a contest.

DFG

In the 18th century professional prize-fighters would tour the country at local fairs. They would give a demonstration bout and would then challenge any of the locals to a contest. Anyone who reckoned he was hard enough would make his challenge by throwing his hat (a man wasn't properly dressed without a hat then - everybody wore one) into the ring. Once he had done that he couldn't back down without being shamed.
