Why is it cowardly? What do you think the purpose of a protest is? Your face does not lend a protest additional credibility, it just makes it easier to target you. The purpose of a protest is to show that people support a cause. Who those people are is irrelevant unless you plan to target them.
It is cowardly to hide behind a mask in a free country where you have nothing to fear of government from protesting.
I do however agree that it is sensible to mask in a country where protesting in and of itself will arrest and mistreatment from the government.
where you have nothing to fear of government from protesting
There is no such thing. Surveillance is something to fear. Tracking is something to fear. Lack of anonymity is in itself something to fear, because anonymity (i.e. privacy) is a right. It’s not just about arrests or physical abuse.
There is nothing “cowardly” about exercising your right to privacy.
If the position you are pushing is truly of no concern to the government, it means either that a) they’re on board with it, so it’s not actually a protest just a rally, or b) you’re not large enough for them to care yet. More likely, you just don’t realize they do actually care.
You’re basically just making a variation on the “if you have nothing to hide, you shouldn’t care about not having privacy” argument.
I fully agree that surveillance is something to fear, but again, if you are living in a free country like Sweden, then you won’t be arrested simply for protesting, vandalism and violence however, those are things you will be arrested for.
A surveillance camera could also prove that you were peaceful if you are caught up in a bad situation if you can be identified.
