The most obvious example would be nearly universal objection against others' suicide, and many against abortion, and some are even converted to certain religions at birth today or have undemocratic rules, traditions and responsibilities forced onto them.
The list could go on and on, but how can we respect others' life (almost universally) while ignoring or prioritizing other things over their free wills? Without free will we'd be nothing but some stones or pile of dirt that moves, or like slaves - which most of us are also against.
So, why isn't there any protest or education against people who're against suicide, or against religion or nationalism teaching to kids, for example? Isn't our free will just as important as life itself, if not more so? And if it is, then anything against our free will should be seen as serious violation like murder, and as of now many governments are committing mass murder (of the minds)?
