Hitch Your Wagon to a Star?

 On March 26. 1997 39 members of the Heaven's Gate cult committed suicide in an attempt to catch a ride with a spaceship hiding in the wake of the Hale-Bopp comet.  Had authorities known of these plans would they have been justified in arresting the cult members to prevent their deaths?  After all, police officers forcibly prevent suicides all the time?  What about a Jehovah Witness who refuses a blood transfusion for a life saving operation?  Should the state force him or her to have the operation to save her or his life?  What about a mountain climber who wants to ascend a dangerous Himalayan mountain peak in the middle of winter?  Would authorities be justified in arresting her or him to prevent such a foolhardy ascent?  Or do individuals have a right to engage in harmful behavior that is meaningful to them?

Legitimate Protest?

 In February, 2022 a "freedom convoy" of truckers, protesting a new rule requiring truck drivers crossing the Canadian/United States to be vaccinated against COVID-19, blocked city streets in and around the Parliament in Ottawa, Canada.  The parked trucks and other makeshift structures effectively impeded traffic throughout the city and has lasted from over a week.  Is this a form of legitimate protest?  What would Mill say -- and do you agree?

An Internet of Hate

A white supremacy group has a website and uses social media to spread their hateful views about race, to recruit new members and raise money for their causes.  While social media organizations like Twitter and Facebook have banned the group because of their content, social media without a content policy allow them to use their services.  Even though it is difficult to make a direct causal connection, incidents of racial violence have spiked since this group has been active.  

Should the state (either the national government or a state government) be legally permitted to ban this group from the internet?  What would Mill say?  Would he be correct?
