Read this excerpt from Patrick Henry's speech "Give Me Liberty or Give Me Death." What is the main idea of the text?
We have petitioned; we have remonstrated; we have supplicated; we have prostrated ourselves before the throne, and have implored its interposition to arrest the tyrannical hands of the ministry and Parliament. Our petitions have been slighted; our remonstrances have produced additional violence and insult; our supplications have been disregarded and we have been spurned, with contempt, from the foot of the throne! In vain, after these things, may we indulge the fond hope of peace and reconciliation. There is no longer any room for hope. If we wish to be free-if we mean to preserve inviolate those inestimable privileges for which we have been so long contending—if we mean not basely to abandon the noble struggle in which we have been so long engaged, and which we have pledged ourselves never to abandon until the glorious object of our contest shall be obtained--we must fight! I repeat it, sir, we must fight! An appeal to arms and to the God of hosts is all that is left us!
