Why'all lives matter' iscontroversial

Changing the lyrics of anational anthem is consideredhighly inappropriate.

But the term "all lives matter" has become particularly controversial because it's seen as a response to the Black Lives Matter movement, which campaigns against racism and police brutality directed toward the black community.

"All lives matter" has beensuggested by some as a more inclusive title for the Black Lives Matter movement.

But it also implies that all lives are equally at risk, despite numerous studies that show black men are much more likely to be killed by police officers in the U.S.

Many argue it minimizes the systemic issues of racism that the black community is dealing with, particularly in the U.S.

While some black celebrities, includingFetty Wap andJanet Jackson, haveused the term "all lives matter," they've faced a tremendous amount of backlash as a result.

How did people react?

Although the audio wasn't crystalclear at the park, many fans reacted with surprise.

While it wasn't shown live on American television, reaction was swift and severe in Canada, where the anthem was broadcast.

What happens next?

The Tenors calledPereira's actions "extremely selfish" in their statement and said hewon't be performing with the group"until further notice."

Arepresentative for The Tenors, AdrienneKakoullis, told CBC News no one from the group would be available for an interview and wouldn't respond to any followup questions.
