The Dominion killed billions, too,
ProtoAvatar--and you didn't seem to think it sould be justified to use genocide against
them.
Again, you specifically said--in no uncertain terms--that if a race is capable of using genocide against an enemy,
it therefore is also capable of using "better" methods to defeat said enemy.
And yet you now claim that, because Picard tried an alternative to genocide, he is guilty of the deaths of the billions upon billions slaughtered/assimilated by the Borg.
