The problem lies with BLM being a Marxist/Communist organisation. The problems are many many of their views from wanting to defund the Police, Wanting to completely change how we live today by breaking up the nuclear family. Just last week they are on the streets of America burning the stars and stripes while hailing the Cuba flag. It is such a hard organisation to get on board with imo and that will be why people dont like others taking the knee.
Also we have seen what the UK BLM thinks with one of their main persons in the UK Sasha Johnson's famous tweet.
I wouldnt boo our players taking the knee (Our players have had far far worse abuse directed at them than boo's over the years ffs, You gotta feel for Charlie Adam the abuse he used to take far worse than a few boo's) but id much rather we stopped as what does taking such a political stance before 90mins of football actually achieve?
How often in this country have we had rammed down our throats religion and politics have no place in football?
