That's precisely why it bothers me. Increased desensitization isn't going to do society any favours
but it will just continue because of the way we deal with things. We're exposed to violent images every day and people just say "eh no big deal". Children see this shit every day. My niece overhead something about someone being suicidal on tv or something, and me and my sister were like "uh oh...." and then my 8 year old niece says "what? he just said he wanted to kill himself" as if it's not a big deal.
The way we avoid topics like this and just let the images fester in our childrens minds before consuming more violent media in the early teens years, yeah desensitisation is a huge issue that people just like to ignore because it's easier. I can't really talk though because I do the same, avoid all awkward situations like the plague.
