I was and am being perfectly civil, don't abuse your mod powers.
Funny you mention me being from another country, I was born and raised in the UK and have a British passport. So I am perfectly knowledgable about the place mind you.
Yes, those allegations were stupid. You can call them evil, but just because someone is evil and Muslim doesn't mean they are the khawarij. In order to be considered part of the Khawarij, these attackers would have had to do a lot more than just shoot people. They would have to consider people kafir purely for sinning too much (or committing any sin at all), they would have to be soft with the kuffar and hard on the disbelievers, they would have to have great Islamic knowledge and recitation capability, they would have to consider all other interpretations as of Islam as the equivalence of kufr, etc. There are a bunch of characteristics that need to be fulfilled. These men don't fit the label you give them because they don't have all the characteristics.
No you were not being civil and you are still being rude, and I explained to you why I gave him the kwarij tag.
I'm surprised that being born and raised in the UK you know very little of the aqeedah they follow. Right, firstly one of his family members gave an interview today saying how he was called a kaffir by him for not having beard. In actual fact the group believe that issues that are quite trivial take you out of the fold of islam e.g. Voting. As for sins it's much worse. The group also clearly states that Sufi, Brelvis, Shia and other groups are infidels. They have also made takfir on Ikwan and other politically minded groups. Butt is actually on record for calling Muslims who condemned Lee Rigby's murder infidels. As for being knowledgable not all of the Kwarij were, so that is not a key trait. They've always been hard on fellow believers, and as for being soft on disbelievers the Kwarij also fought in jihad.
Like I said before I've met these men and don't just put baseless accusations on people. If you choose to call that stupid then that's your unwise choice.
