If this post isn't a violation of our rules (pending discussion), it is
deep into the gray area. People would do well to avoid similar statements.
The religion of the people involved here simply does not matter at all—beyond possibly influencing the desired target (which I believe was at least part of
@horsesboy's point).
The core issue is violent extremism—which, to be clear, regularly comes in
MANY flavors. There is zero reason for this discussion to dive any deeper than that. Someone, personally, believed something stupid, they concluded that stupid, personal belief needed to be enforced on the people around them, and they were radicalized to believe they needed to be the enforcement mechanism—hence, violence. A tale as old as time.
In this case, the stupid belief was likely related to these individuals' faiths, but, in an alternate timeline, it could have just as easily been that they were violent, extremist flat earthers who believed Cedar Point was promoting globe theory and it was their job to silence this prominent opposition.
So yeah, religion is irrelevant to this conversation. All that matters here is violent radicalization broadly.
