When Christ said to love your enemies it goes without saying that He believed we would have enemies. I think not. Especially if you go back to the beginning of the Sermon on the Mount. Blessed are you when people shall revile you and persecute you and utter all kinds of evil against you falsely on my account. It seems that Jesus believed that those who are willing to publicly demonstrate their conviction in the veracity of the Word of God would be vilified and opposed.
Love is the ultimate expression of activism.
He does not tell the advocates of truth and righteousness to reduce their persecution by toning down their message and become accepting of their tormentors. Love holds out for the truth to the end. You are not loving a Muslim by affirming his or her belief in Allah and their unbelief in Jesus as the Son of God. You are not loving a homosexual by affirming his or her sin and accepting as normative their behavior. He was not affirming and accepting adultery.
