1 person can do something. Things do make a change....
I will revise this late but keep the intention here
How and where you stand your ground is important or just not abandoning always because mass isn't behind you (it's a bully tactic but 1 problem person can either attract too much attention (which is bad) or can be a problem for them and not give too much ground / human blockade (good) )
Although waiting for mass is also part of it everything and part of the whole- it's not the only thing.
So I write this with intention that keeping the intention is important and sticking your flag in the ground / drawing the line,
Not leaving things unguarded or left unkept.
Justice is a upkeep which we need to stand by even if it's at home thinking 'how can it be symbolic or more'.
I'm also advocating choosing which level to start or gear you select but driving change (like a screw-driver) is what I mean, even if you have to screw in screw yourself! Incrementing or 1 screw at a time does it over time or make your flag and stand there.
I still encourage you to keep your intentions in a forward gear or flanking thing - not too defensive. Bodies in the way do count. Absorbing their time does work and save others.
Symbolically one person like tank man or Greta Thunberg can really say it and make it stick or on a personal level making friends with as many people as possible.
Regardless of the aforementioned politics of those individuals or what happened it's about what you believe in.... and also helps correct yourself in preparing or practising moves without being always 'all in' or just being 'out' of the picture of participation (on whatever level you can).
