Concerning your first point - apparently you did not read the entire thread, preferring to jump in midpoint, I guess.  I merely asked Sr. Rose for clarification.  Michael Binder answered, and I asked more questions.  More than one is plural.
2). If no one here denies personal responsibility, then why not simply say so instead of lobbing snarky remarks back?  
3). Your remark about "contributing factors" apparently concerned manufacturers and profits.  I have not disagreed with that - my point is, however, that they are not the ONLY factors in the scourge of gun violence, and that appropriate measures also have to be taken concerning personal responsibility.

You may think the answer is obvious, but it is not. The typical mantra here seems to be to blame someone else for problems - therefore corporations & profits are to blame - not the one who pulls the trigger...unless a police officer.  Then the police officer is the one to blame.
