Oh my god.
You know what, I'm not refuting anything, I'm just leaving my personal take.
Yes, this man is a terrorist. He was a terrorist for a far-right cause. Was it wrong? Yes. Is he any different from ISIS? No. Was the terrorist attack a good thing? Absolutely not. Was it aimed at the right people? Of course it wasn't. But it was a revenge attack.
Of course, he is responsible for it. He thought about doing it, and he did do it. Nobody forced him to. But in his mind this was revenge for ISIS and other Islamic extremism. It wouldn't have happened if Islamic extremism didn't happen in the west.
Now, many people would say he's delusional and naive for thinking that these innocent muslims were the ones who needed to be punished for the terrorist attacks. I disagree. I think that he knew these muslims were innocent. The important part is that it was a revenge attack. Islamic extremists have killed thousands of innocent people in the west over the last 20-30 years. So perhaps in his mind, he was killing innocent Muslims as a tit for tat scenario, 'see how it feels to have innocent people in YOUR community be killed'. But then you get to the problem that ISIS and other Islamist organisations are probably happy that this attack took place, because these moderate muslims were just as heretic and non-Islamic in their minds as the people in the west they've attacked. We'll never truly know his thought process for sure.
Of course, this should go without saying but that doesn't justify the attacks. It is still a very reprehensible act to kill innocent people. This man deserves all the arse-rapes and beatings he will get in prison.
Unfortunately you can't bury your head in the sand and say this was a completely unprovoked attack that had nothing to do with the actions of others in power. Open borders, uncontrolled immigration, Islamic extremism, attitudes towards Islamic extremism and uncontrolled immigration, and the general reluctance to do anything about Islamic criminals and extremists/jihadists in fears of being labelled racist and Islamophobic (Rotherham grooming gangs are one example, heard about a similar case in Telford, the labelling of extremism watchlists as Islamophobic because they watch suspected extremists/jihadists, we could go on) all contributed to this man's feeling of being attacked by Islam. People will say I'm making excuses for him, but plenty of people use the same excuses of western intervention in the Middle East as fuelling extremism which it undoubtedly has, and I don't see these reasons behind him committing this act any different than saying that about Islamic terrorism.
P.S. Before some idiot pulls me up on calling it 'Islamic', yes it is Islamic, I don't care about extremists supposedly not following true Islam, what matters is that they are Islamic extremists and jihadists, that is what they are so I will call them that, if you are a muslim and don't agree with extremism, then that's great to hear you're a normal sane person, the fact that you're a moderate means you are the opposite of an extremist, so the term 'Islamic extremist/Islamist/Jihadist' tells itself that you're not part of that group.
Sorry for the mini-rant at the end
