Is this what do you understand as "loving" your enemy?
Are you sure the "love" Jesus mentioned is the "love" you understand?
I studied this story hard and investigated it because it was seemingly out of character of Jesus.
What had happened was that the Jews had turned the Temple into a scheeming scamming marketplace. This was the location for the Samaritan's to pray at the Temple. They believed in God but couldn't get to the inner courtyard to pray like the Jews could...they had to stand (if they could) next to the merchants selling overpriced animals and moneychangers haggling over exchange rates to pray with security guards protecting the moneychangers...giving everyone the evil eye.
Even still this marketplace was full of Jews who later would be trapped in the Temple when Rome besieged the Temple. Jesus was trying to save the average working person even though they were working in the wrong place.
People don't give up money easily...but Jesus was still trying to save them from a much more serious fate...and was resorting to more corporal methods to try to save them.
