Yeah, those organizations are not the same other than they are all terrorist organizations. They don't even get along unless it's an "the enemy of my enemy is my friend" situation. There are factions within those groups. ISIS-K is an offshoot of ISIS. Some factions within al Qaeda have different ideas of what the group as a whole is about even though their "bigger picture" is death to the West.

It's just like any other group. Christianity has so many denominations it's hard to count and though they all have the same overall belief they go about it all in very different ways. Same with Islam. Same with alt-left and alt-right groups. Same within the political parties. Not all democrats are progressives and not all conservatives are religious.
