Sufyan: I am muslim through conversion, previously I was what could be called agnostic. More specifically I am what you would probably identify as Sunni Muslim, though to us it only means "not shia, not sufi" (they are the ones who differentiate themselves from others). Truth is the rabbit hole goes much deeper if you want to pick apart and sort different scholarly ideas under different labels. To most muslims this isn't a concious decision, you live life in broad strokes, not by analysing every single decision and principle and catalogising them under different names.
See, this is what a lot of people forget - namely that the vast majority of Muslims go through life living life more according to the principles that are passed down to them as opposed to actual religious tenets. I doubt many Muslims have even read the Qu'ran, let alone internalised it. Many in the Middle East can't even read. Over time, many of these cultural principles have become confused with religious principles. The way they conduct themselves is largely an instinctive pattern congruent with how they were raised as opposed to any religious scripture.
Sufyan: I have absolutely zero concern about racist and bigoted trolls on the internet, though I think the FBI should probably check up on infinite9 for promoting terrorism just to be sure he isn't part of a network of actual race war fetishists (when is that shit going down, by the way? You've been preparing for decades by now!). I see trolls every day, and I see a fair bit of shameful racism in my country, mostly from older people (55+). No one has ever laid hands on me, my family or my property, though there have been a couple of disturbing non-physical confrontations over the years. The one I thoroughly regret not reporting was when a ~60yo man approached my wife and played a sound clip on his phone where a call to prayer is cut short by two shotgun blasts. I was so shocked and uncomfortable with it that I couldn't speak before he walked away. Tried to pretend it was nothing, just some stupid asshole thing, and to forget about it. That, I regret.
The problem is that people like infinite9 and people who actually put such threats into practice are the product of racist and bigoted trolls online. Actual terrorists feed off of the approval of such people. And honestly, I respect and admire your restraint - I probably wouldn't have shown the same reticence.
In fact, I already showed my lack of reticence once when my wife and I were walking along a street in the UK at one point, speaking in German, and this pair of thugs decided to shadow us, doing Hitler salutes and singing "Deutschland über alles". I turned around to give them a threatening glare and walked on, and they persisted anyway, so I just instinctively punched one of them in the face and broke his nose. In doing so, I risked the wrath of British justice (nothing ever came of it), but honestly, although my reaction was instinctive, I have no regrets about it.
So while I imagine that you probably wouldn't have reacted in the same way as I did, I can certainly understand your frustration at not having acted. Honestly, he sounds like a bitter old racist that probably wouldn't have done much else, but I think reporting him to the cops for making a credible terror threat would have been enough to think twice about harassing someone on the street like that again. Leaving such acts unpunished only makes things worse.
Sufyan: Btw I never block people online, not even bigots, because they tend to block me first after dumping their garbage where I can see it.
Typical. They're quick to dish out all this vitriol, but not so quick to actually face the consequences of their actions. Shows them for the cowards that they are.
