David25... Yeah dont think too hard about it....much ideology is necessary and only 2/3rds of people can do that, 1/3rd very very well, in the real world of political understanding not the psychotic kind pushed through cultural Marxist dogmas modernly Tarrant was a supremacist that is cut and dry and Islam is a supremacist religious and political ideology that is also cut and dry.
Also dont worry too about the peoples feelings...feelings are a poor substitute for teneted emotion in psychological science...actually they are not not even a poor substitute...feelings as many peoples only grade of emotion and display are gamed all the time when appealing to any collectivist ideology...actually when it's political it is pretty much about the deepest emotional all such ideologues are capable given their ideology is their personality.
That is actually why identical and far worse tragedy's cannot touch many people unless it is also politically/ideologically expedient for it to do so...they need something to gain and and therefore raise dopamine...it's very important to them.
Human frontal lobes have not changed in thousands of years and will probably devolve somewhat over the next thousands.
