Checks your comment history:

• ‘the indigenous genocide in North America lifted a lot of Europeans out of poverty’
• ‘the Ukraine bombing of Donbas in it’s civil war was justified and not an ethnic cleansing’
• ‘the ruzzian orks deserve it’
• ‘send all possible Ukrainians to their deaths over a line on a map’

So “celebrating the killing a lot of people” is only “sick and twisted” when it’s USians dying. Indigenous people and Russians don’t count and should be celebrated because Europeans want the land. Typical liberal.
And you love to throw around “whataboutism” so that’ll come out in a reply to smooth over your calls for bloodlust being justified but jokes about 9/11 are still ‘too soon’.
