Yes. I am ok with that system. I wouldn't be OK if the government was regulating which way the political winds blow.
Here was the phrasing of the question:
Which statement is closest to your own: black lives matter or all lives matter? Or does neither statement reflect your point of view?
This is a weird way of putting it. If I were given this question, I would answer "all lives matter," as would most members of the BLM movement. The question should instead be something along the lines of, "Do you feel that the black lives matter movement excludes members of a different race?"
Saying, "All lives matter" without a specific context is OK. Saying it in response, or to challenge the BLM movement implies that there is some sort of disagreement there. It takes up a different meaning.
