You missed the point.
Hamas can claim to be following the written words in the Koran - "kill the infidels"
The teaching of Jesus in contrast - "Love your enemies"
Does that mean that the teachings of Jesus are that Christians should love Hamas as opposed to trying to inflict violence on Hamas?
How does "loving Hamas" fit in with this bit below in your quote from Voice for Justice:
It is entirely right that Israel take appropriate and proportionate action to defend itself from threat, and those who are genuine in their calls for peace should, first and foremost, be condemning not them, but Hamas – for the good of both Jews and Palestinians alike. For genuine peace, protestors should be calling for the condemnation and removal of all terrorists from Gaza and the Palestinian territories. Because only then will the civilian population of both States be able to live in peace. Seems like you are supporting fighting Hamas rather than loving Hamas?
Based on the evidence of Israeli aggression since 1948, it's not just Hamas that is the obstacle to peace. For the civilian populations of Israel and the Palestinian territories illegally occupied by Israel to live in peace, Israel needs to end its illegal occupation, settlement expansion, land grab and acts of terrorism against Palestinian civilians.
The Quran seems to express a legal or moral principle that humans can fight against oppression and kill their oppressors rather than loving their oppressors. For example it says:
“And slay them wherever ye catch them, and turn them out from where they have Turned you out; for tumult and oppression are worse than slaughter; but fight them not at the Sacred Mosque, unless they (first) fight you there; but if they fight you, slay them. Such is the reward of those who suppress faith. (2:191).
But it's a bit more complex than cherry-picking Quranic verses as there is context to consider, as there is with any legal decisions about justifications for violence.
