SarasotaSlim - I already explained the reason Muslims kill other Muslims to him. These are the 3 reasons.
1. Intra-Muslim conflicts - Shia vs. Sunni - fundamentalists vs. moderates vs. apostates - Kharijites, Wahhabis, etc. or ethnic conflicts, or economics, or tribalism
2. Jihad applies to other Muslims too. Not all Muslims are considered equal according to the Quran. The Quran calls ‘not true Muslims,’ “hypocrites.”
3. Muslims kill the easiest and most available targets. Not many Christians and J3ws to kill in Muslim countries. It’s really difficult to kill Christians and J3ws in Afghanistan, Egypt, Iran, Iraq, Libya, Pakistan, Palestine, Syria, Turkey, and Saudi Arabia when the countries are over 90 to 100 percent Muslim.
Muslims have to go to psycho liberal lands to find targets. It’s much easier for Muslims to wage Jihad against US soldiers on Muslim lands and to kill other Muslims in the name of jihad than it is to find Christians and J3ws to slaughter in the name of Allah over there.
SarasotaSlim, here are some Quran verses that expand on your point.
https://corpus.quran.com/translation.jsp?chapter=17&verse=33And do not kill anyone which Allah has forbidden, except for a just cause. And whoever is killed (intentionally with hostility and oppression and not by mistake), We have given his heir the authority [(to demand Qisas, Law of Equality in punishment or to forgive, or to take Diya (blood money)]. But let him not exceed limits in the matter of taking life (i.e he should not kill except the killer only). Verily, he is helped (by the Islamic law).
https://corpus.quran.com/translation.jsp?chapter=9&verse=73O Prophet (Muhammad SAW)! Strive hard against the disbelievers and the
hypocrites, and be harsh against them, their abode is Hell, - and worst indeed is that destination.
https://corpus.quran.com/translation.jsp?chapter=9&verse=56They swear by Allah that they are truly of you while they are not of you, but they are a people
(hypocrites) who are afraid (that you may kill them).
https://corpus.quran.com/translation.jsp?chapter=9&verse=68Allah has promised the
hypocrites; men and women, and the disbelievers, the Fire of Hell, therein shall they abide. It will suffice them. Allah has cursed them and for them is the lasting torment.
