The analogy is apt. #alllivesmatter belittles the concerns of black people and the disproportionate danger they face interacting with police. Likewise, cyclists are disproportionately at risk of serious harm while on the road. Not that complicated. Black people are 'whining' because they have legitimate concerns for their safety. Cyclists do as well. And the laws are written in such a way that blacks/cyclists deaths can be easily swept under the rug.
Stop whining is not helpful advice. It means shut up.
Wow. Late night rant, perhaps I should have run as the Republican candidate for POTUS.
