It may well have done. But just because it’s being treated as a terrorist attack doesn’t mean it automatically is a religiously motivated one. To automatically link the two isn’t helpful.
In fact according to this article in the US “Between 2009 and early 2019, 73.3% of fatalities resulting from a terrorist attack were from right-wing extremists, compared to only 23.4% by Islamic extremists”
Again. It may well have been religiously motivated (although I would argue Islamism is a political movement rather than a religious one but that’s a whole other conversation) but to automatically make the connection that terrorist = religious motivation is unhelpful at best, and potentially harmful at worst; it is the conflation of Muslim = terrorist that is driving a lot of the right wing extremism and terrorism that has been rising in the last 20 years.
