You're talking about two different things. I have no problem with people who feel they have to protect their anonymity in a protest.
I do have a problem with people who wear a mask so they can commit violent acts, or threaten people.
I also have a problem because that disguise creates the perfect cameoflage for cops to infiltrate and undermine protest.
And needless to say, I have a big problem with cops who do wear that mask and commit that violence.
It's the violence I have a problem with, and if I saw someone threatening people or breaking up stuff I would do what I could to prevent it or turn them in without a thought. I oppose police using those tactics against legitimate protest; how can I justify it just because it is done by someone who claims to share my views?
