I have a crusade against fondant also shortening. There's no reason why wedding cakes can't taste good if you know what you're doing.
My own early crusade for same-sex marriage for example is now mainstream gay politics. It wasn't when I started.
Every war results from the struggle for markets and spheres of influence and every war is sold to the public by professional liars and totally sincere religious maniacs as a Holy Crusade to save God and Goodness from Satan and Evil.
Ever since the Crusades when Christians from western Europe were fighting holy wars against Muslims in the near east western people have often perceived Islam as a violent and intolerant faith - even though when this prejudice took root Islam had a better record of tolerance than Christianity.
In religious and in secular affairs the more fervent beliefs attract followers. If you are a moderate in any respect - if you're a moderate on abortion if you're a moderate on gun control or if you're a moderate in your religious faith - it doesn't evolve into a crusade where you're either right or wrong good or bad with us or against us.
