Mental health is no joke. She shouldn't had any access to any guns. To be fair though, I haven't read about how she acquired the gun.
WWII Allies killed Nazis to save humans. They weren't shocked to realize that Nazis were humans.
So yes, that's exactly how it was.
You seem to be confusing respect for animal life with pacifism. Fighting to defend the helpless is company with caring for the helpless. Soldiers kill people to defend their countrymen.
I doubt being vegan is the key here.
Though there is a fair amount of bullying, through ad-homenim attacks or idiots just trying to wind people up for shits & giggles. There are also some with a persecution complex that seem to take even the slightest criticism as a violent attack. This is not constrained to veganism though: there are similarly unhinged people in many walks of life.

I expect this is the more important factor. Being a vegan is likely a consequence of her strong feelings in this area (the fact that some are highlighting the vegan thing is an example of the bullying I mention above). Animal rights is a very emotive area and some people (a few, but a very active and vocal few) get dangerously passionate about it to the point of losing all view of any other logic or moral sensibility (like not killing human animals).
> a workout video being age-gated: who would oppose that video?
I've not seen the video in question so I can't make specific guesses, but there are a couple of possibilities that spring to mind:
* Some people are very puritan about the showing of skin and so forth, perhaps there was a complaint about that sort of thing?
* Was anything potentially divisive said during the workout clip, even in passing? Given her apparent anger at the world that is not unlikely.
* It could just be someone that disagrees with her views on something else. Down-voting and reporting entirely unrelated content in response to something else is an immature but very common reaction.
I’m not a vegan, but I don’t see the point in opposing them. Other than the banter about how in-your-face they can be, do people violently oppose vegans, or animal rights activists? She was upset over a workout video being age-gated: who would oppose that video?
