The BLM movement has been hijacked by a small number of opportunist thugs who'll hide by the name as they know any opposition will be met with "U AGAINST BLACK LIVES MATTER DEN M8???"
I have no problem with peaceful protests (albeit not in a global pandemic) however I'll be dissapointed if the silent majority continue to raise no objection in these thugs attacking innocent people and destroy whatever they seem fit.
As said there's no need to. If it continues and stays violent, the government and police lose patience, crackdown on it and its no longer politically expedient to be sympathetic with the cause.
If they had sense, BLM leaders should be strongly wording against further protests as much as possible and backing away. If the far right have any sense, they'll be goading them into continuing as much as possible.
The best result - for everyone - is that the riots stop and political engagement occurs now with the leadership of the movement and government to enact real societal change instead of pulling down statues for some reason.
