A lot of what these protests are trying to do is make it harder to ignore the reality of what is happening.

Now I agree these kind of protests don't gain support. But they're not trying to win support: they're trying to make people aware of the problem as one that shosuldn't be ignored.

The gamble is the cause is important enough and sympathetic enough that forcing people to be aware of it might get people towards political action. Even if it is just calling their representstive and going 'wtf'.

For Americans every dollar we earn at work and every cent of tax we pay is a contributing factor in the conflict. But many are aware and think that is just fine. That is my personal concern with this protest: a lot of Americans are completely stoked about it and protesting just makes them shrug and go 'purple hairs lol'.
