Sometimes protest must cost the protester something to prove a point, if not - as you point out - many people will be violently detained and assaulted by the law without restraint.

Civil rights protesters for generations have known that getting beaten and unjustly charged are probable short term outcomes while long term justice is on the way. They weigh that they are willing to endure that for the greater good. Yielding to powerful people and injustice because it is unjust is a choice that you can make, but don’t call other people wishful thinkers that need to get a “fucking clue” for being willing to do the thing that you are fearful of.
