I never said it's "fighting for freedom" not the kind of freedom people want these days. But against oppression. Even oppression of non-Muslims.
Why doesn't "fighting for the freedom to practice Islam" make sense? "Fighting to practice Islam" would apply as well. But that would insinuate they are fighting for themselves only.
For freedom to fit in there it would have to be "Fighting for the freedom
of individuals to practice Islam
or not." It has to do with the importance and rich history of the word freedom, and it has specific provisions. The thing is that if you aren't fighting for individuals to choose Islam or not, then its not fighting for freedom. Its fighting for Islam.
Freedom starts with the concept of someone who has moral ability to choose, so its someone who doesn't need to be told what to do, influenced by the shock of the 12th century in England when the nobles enslaved the populace to build castles and tortured people in dungeons while the king ignored everything that was going on. Because of things like this people began to seriously consider the idea of a free and equal society, because they had been betrayed by the royals and the nobles. They discovered that there was no basis for the claim to moral superiority and saw that the titles were empty. They stopped by degrees believing in the pecking order and saw it as more of a practicality than a moral hierarchy. The laws gradually changed to recognize this as the term freedom grew in prominence and depth of meaning.
Freedom is a different way of living than the old ways. In the old days people referred to their betters as masters, but as the concept of freedom grew and as they developed its philosophy they gradually stopped doing that. The belief faded that a noble person was a better quality of human having some special quality which empowered them to make decisions for others. It became a mistrusted idea, then an antiquated one.
These days superiority is only acceptable in the military. Soldiers are required to call the officers their superiors as part of military discipline. The soldier doesn't choose when to kill, because the officer does. Therefore the officer is the superior in rank, the one making the moral choices. Once upon a time the entire world was ordered that way, and you had a pecking order of betters from the worst humans to the best. If your master told you to kill someone you just did it, because it was their responsibility to think not yours. If they said drop your pants you dropped your pants.
