They might well be the case, but I also think these protests do get infiltrated by people opposed to the cause - and are trying to undermine it.
What's to stop far right activists disguising their appearance and committing acts of violence?
The Daily Mail used a very selective clip of Boris Johnson talking about Black Lives Matters. I don't like the man, but he actually made a good 5 minute speech, but of course - as Prime Minister he condoned the violence and said this was not acceptable. This is the only section of his speech the Daily Mail highlighted in both their headline and on their video clip.
It's subversive and deliberate - and it's done to undermine the message of the protests.
