I am hugely in favour of freedom of speech, but this is abusing that hard-won privilege.
I am also in favour of peaceful protest, but that really only applies if the message is appropriate, and the demo is aimed at, and affects the individuals involved directly.
None of those provisos apply here.
For a start, ALL lives matter.
Secondly, the notion of taking a concept which has originated in America, and bringing it over here in this way is not at all helpful to the cause they are attempting to support.
And finally, the disruption of the lives, jobs and holidays of people who may very well (and who wouldn't!) support the ideals they promote is simply unacceptable.
The BLM organisation has not covered itself in glory today.
