>> "Slippery slope" is the term used to describe the fallacy of logic in that sentence. Who must perform this proactive protection? Why should/must they do it? What constitutes "vulnerable"? This sounds like the musings of a privileged youth. Fun fact: "Slippery slope" is the term used to describe the fallacy of logic in your sentences. The slippery slope fallacy lies in you rejecting the -- admittetly vague -- claim "Vulnerable people must be proactively protected." just because you can imagine that bad things might happen if this mind-set was applied excessively. This is a fallacy of logic, since it leads you to reject a claim just because it is not as precise as you'd like it to be. However, a claim isn't invalid per se just because it is vague.
