SJWs are going to try and claim this is the same thing as radicalised muslim doing it... it may be the same act that some have done but the reasons and the circumstances are not hence it's not the same at all(then again it's a bit of an ask to expect SJW's to be impartial and apply some common sense). They can call it what they want in the press(lone wolf, lone terrorist... key word being lone though because this was his decision), I doubt we will know his reasons for it but as a guess probably lost his marbles sick of all these terrorist attacks fuelled by a hatred of western culture.
I'm not sure any sort of debate that includes the phrase 'SJWs' is worthy of any consideration, regardless of viewpoint.
The rest of a post could be the most enlightening and intelligent prose/commentary ever written but it is undeniable that anyone using the phrase 'SJWs' has undoubtedly been far too influenced by the internet and corners of internet culture where their ability to recognise what constitutes reasoned debate will be seriously impaired. The simple lack of self awareness that would lead someone to think that such a phrase is anything other than an embarrassment outside of their usual internet dwellings would have to lead someone to ignore the rest of the post.
Which is probably a shame, as there will be plenty of intelligent people who are being totally and utterly lost to intelligent debate and could contribute to it, but they are losing sight of the real world and how to debate with real people in their internet slums.
