I agree people shouldn't cross out black lives matter.

However, if you're going to let them write "black lives matter," you should also allow people to write "all lives matter."

If our society has reached a point of guilt, where we can no longer acknowledge that all lives matter, and doing so is "racist," that means blacks (and allies) will have become the new de facto racist group.
