''What’s your opinion of sports teams postponing games either to recognize or protest a social issue cause?''
There was a sporting boycott of South Africa during the apartheid era.
And a boycott of the Moscow Olympics 1980 after the Soviet/Afghan war by many nations
and a retaliatory one of the 1984 LA Olympics by mainly Eastern bloc nations.
It does seem to happen.
One part of me thinks that sports occasions should rise above political differences but I can also see why some would not want to carry on as if nothing had happened.
