you are deploying your usual tu quoque/ hypocrisy fallacy (argument) whenever someone criticises the actions of a group. rather than dealing squarely with the issue of isis savagery and the folks who promote it. let's stick with isis.
for myself, folks who starve yazidi men, women and children on a mountain, behead journalists and film themselves doing so, destroy ancient tombs and statues, bury women and children alive, shoot people they defeat are indefensible. and the imams who encourage them are vile monsters. it's kinda simple.
but perhaps you want to mount a defence.
