I'm not trying to start the 'but what about violence1@#' train of debate yet again since that has been refuted countless times, but if I may float an example close to home to many, if we're going to discuss an issue like gun crimes, militarization of police hardware etc., we probably need to take into context any given specific country's gun laws/regulations (e.g. in US vs elsewhere) and general public preconceptions on the issue.
Some people are completely fine with guns being in every household with proper regulation/checks/etc. Other people from other countries find the thought extremely disturbing.
Hence, context.
(And no, I for one think that the rise of moe culture in Japan has ruined a lot of good things, from games, to anime, to Akihabara)
This is honestly just a dime-a-dozen mobage that's honestly kinda tame compared to what they get away with in behemoth FGO.
Speaking of context, the context here really isn't about how it stacks up against what's out there, and a lot more about how it originally was a pretty well-known franchise targeted at children.
Fate as a franchise, for example, really did start off as an adult VN about a dozen years ago.
