IS attacks Hamas, Islamic Jihad in Gaza - so now they are no longer "Islamic extremists"

From Ma'an:

Five car bombs were detonated simultaneously in the center of Gaza City and in its southern neighborhood of Sheikh Radwan Sunday morning leaving two Palestinians injured.

Graffiti on a wall near the bombings read "Daesh," the Arabic acronym for the Islamic State group (IS), although no group has taken official responsibility for the attacks.

Three of the cars were reportedly owned by members of Hamas, while the other two were owned by members of the Islamic Jihad.

Shrapnel from the blasts hit residential houses, shattering windows and injuring two people who were transferred to a local hospital.

No deaths were reported.

Hamas officials have opened an investigation on the explosions.

Since last summer's devastating war in Gaza, there have been growing signs of internal unrest between Hamas security forces and other militant groups, with a string of small-scale explosions.

Many of the more recent attacks are believed to be the work of fringe Salafist groups that have made a name for themselves as unafraid to challenge Hamas, seeking to outbid them in the fight against Israel and the defense of Islam.

There have also been attacks claimed by groups purporting to be from an IS branch in Gaza, although such claims have so far been largely discredited by online militant forums.

Other Arabic media reports six cars blown up.

According to White House thinking, this means we should start allying ourselves with, and maybe arming, Hamas and Islamic Jihad who are bitterly opposed to the more extreme terrorists of IS.

That logic worked for Iran, right?

The President studiously avoids saying that he is against Islamist radicals, but rather opposed to vague "violent extremism."  In the thinking of today's diplomats, pundits and journalists, extremism is not am objective term - something is only extreme where then is nothing more extreme. So Israeli "extremists" are those who want to walk around peacefully on a holy site while Arabs who murder Jews and fire rockets at civilians are "moderates."

If a new Islamist group would appear that is even more reprehensible than IS,  then IS will no longer be "extremist." This is part of how Hamas and Islamic Jihad have gained legitimacy. The PLO is now talking to Islamic Jihad as a potential partner without causing any angst in the West. "Human Rights" NGOs have no problem with their employees openly admiring Islamic terrorists.  You will not find any description of Hamas or Islamic Jihad as being terrorists in the mainstream media even when they take credit for and applaud terror attacks, today, on Jewish civilians.

IS is doing the other terror groups a favor by attacking them.
