They can make me think twice about who I treaty if it's somebody they don't like or somebody they think could somehow threaten me as I may fear that I could be caught up in their "crusade for justice" against them. Now personally I don't care, my nation has been wrecked a number of times and even wiped from the planet on one occassion before. Nothing new or frightening there, it can be rebuilt. Some though, won't ally with friends for fear that it will make NPO notice them and put them on their list as well. Or some such radical, crazy belief that is likely just as insane as your mindless devotion.
However, you are right. They don't screw with my infra purchases. I concede the point. Though they have destroyed my precious infras many times but that just made it cheaper and easy to buy so no worries.
