Example Input: Roberta B. Rinehart - in this country we don't make decisions based on personal preference, but on the Constitution and the basis of natural rights. I'm sorry you're afraid of guns, but your fear should not deprive other people of their natural right to protect themselves in the event of an attack much like what you describe. Rich people who can afford armed guards should not be the only ones who have a hope of being safe in this country.

And, no, getting rid of all the guns would not stop violence from occurring ... it would only make an uneven scenario where the bigger and stronger can overpower the smaller and weaker. Guns are an equalizer and as a woman who avoided being raped because of a gun, I refuse to allow you to make me a victim.
Example Output:
Yes
