Have there been generations that have been anti war? Like teens not wanting to understand the warrior culture?
With humans, we sometimes make antiwar propaganda out of hatred for the violence of it. From music, to paintings, to even graphic animation. Are there some Sangheili that hate war, and try to fight against it, or is it just treated as a bitter reality?
Rejection of warfare has never been common, among Sangheili. Our history tells us we warred with one another often and well long before the San'Shyuum made it our species' entire purpose.
This is not to say that none of my people have ever turned their backs on war as a solution, but that their number has been vanishingly few.
For our youths, it is traditional that only males were taught the battle arts. Females learned defense of self and home, but were more free to devote study to other pursuits. These were always considered secondary to military service.
Some young men refused to become soldiers. The Covenant could not make one of an unwilling or unable recruit, but it would mark him for life as somehow defective: he was a coward too weak of blood, a nonbeliever too weak of faith, or an invalid too weak of body. Any of these was a great shame to a clan, and a son's failure could worsen prospects for his cousins.
So was the thinking, for many years. So remains the thinking, among some clans.
As things are now, Sangheili must still fight. Our place in the galaxy is not certain if we are not able to hold it. But I hope the young ones we raise now will be stronger because those who fight do so by choice.
And they will be supported by those who cultivate the talents we neglected for too long.
