There are two kind of people in this world, those who see the world only as black and white and those you don't..you are the former
You have absolutely zero authority to say who is or who isn't a Muslim or which acts come under Islam and which don't..neither does any other person alive.
Islam isn't anyone's property, no one gets to define it...Earlier in the thread, you called ahmadis non-muslims. Soon you might do the same for Shia muslims. By the end you will be left with a handful of people who you think are the only ones inside the strict boundaries set forth in "your definition" of Islam..but guess what, you don't get to decide that.
Islam is an idea, there are no copyrights on ideas. I can become part of a satanist cult tomorrow and still call myself a Muslim, and there is absolutely jackshit you can do about it. Sure, you can tell yourself all you want that i am not a muslim, but you don't have copyright on the word(or its associated ideas) and you can't stop me from using them.
A religion is a living, evolving thing. Over the ages, As Islam spread, it eventually become part of human civilization and the collective human heritage..Its not up to the original followers anymore to decide what it does and doesn't constitute, and it stopped being that way the day Islam started spreading outside Arabia. Just like it not up to the decedents of the Romans to decide what is and what isn't democracy.
And just fyi, i was also raised muslim. Just a less bigoted one than you though.
