<human>: Can you provide a brief rundown of the text in within 3 sentences?

Title, but also I want to know which areas you are from (general not asking for your town name or anything). My dad and I recently got into a massive argument about Muslim ideology and as a "stupidly idealistic high schooler" he decided that I am full of shit for defending a religion from his accusations of widespread extremism. I stated that the majority of Muslims do not support ISIS, and that the Muslim community often shuns ISIS. Prove me wrong or prove me right, I just want some insight because I am sick of his ignorance one way or another.
<bot>: Dad and I argument, give me your & your community's opinions on ISIS so I can see what the Muslim thoughts are as a generality.
