Yes you can. Plenty of time for questions. Plenty of time for answers.
However, BLM is a simple yes or no. Do you resent racism by white people towards black people and will you stand up for black people in their fight against this racism? Do black lives matter to you? It's a simple yes or no. Questions and other alternatives come afterwards.
Twe example responses to "Do you believe that black lives matter?"
1) "Yes, I support BLM but to me the bigger picture is that all lives matter."
2) "I believe all lives matter"
Can you see the difference?
