The perfection of the disciple is a perfection of love, in that he loves freely and unconditionally, even his enemies.  God has not called us to demonize our enemies so that they are not worthy of our love.  He has called us to give them grace, and pray for them.  The mean-spiritedness of so much speech is contrary to biblical teachings.  “Speak evil of no one” Titus 3:2.  We, the unworthy, are called to love the unworthy.

“You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’  But I say to you, love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.  For if you love those who love you, what reward do you have? Do not even the tax collectors do the same?  If you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same?  Therefore you are to be perfect, as your heavenly Father is perfect.”  Matthew 5:43-48 (NASB)
