No, numbers make people take a protest seriously.
If you are discounting a cause based on whether the supporters show their faces or not, that’s just you looking for an excuse.
In my experience if there is a masked protest here in Sweden, it is beacuase people want to riot, even if the initial idea was not to riot, the concept of a masked protest will attract more people who will riot.

You may be living in a country that allows you to protest, but you have created your own mental shackles by buying into an authoritarian narrative against masked protests.
Masks == dangerous potential rioters is not a “free” mindset.
Have you seen people protesting against Nazis in Sweden? That’s the sort of situation where you do not need to fear the state, but the violent and retributive people you are protesting.
