Ultimately, I think you have to name it what it is, which is worship of the culture of death. It's the idea that if you kill enough other people your problems go away. It's basically the same logic whether it comes from Putin, Netanyahu, Isis, Hamas, Trump, or an MTF poster. It's the same kool-aid. It's the 21st century cool-kids philosophy.
Anyone that hews to that old "I came that you may have life, and have it abundantly" stuff? Losers.
