I would never deny anyone the right to their opinion--I would not like a vulgar display of profanity or a direct threat . . . but, if that made the person feel better, more power to them, if the forum allowed.  However, open discourse is our way, not the exception, except to the liberal.  The liberal ideology is a failure and indefensible.  That's why I get a kick out of arguing with the true believers of Marx . . .
