What are acceptable protests in your opinion?

I am referring to Minnesota and the general frustration that people have with the treatment of black people by law enforcement officers.

There is a large segment of the population, heavily represented on this board I might add, that has condemned both these riots and peaceful protesting by athletes.

When it was peaceful - it was considered too disrespectful, attention-whoring, not going to lead to any real change. When it is violent it is considered dangerous, counter-productive to good change, and only hurting the communities.

So I ask - what would be acceptable forms of protest in your opinion?

This will get derailed quickly but let's start by addressing a few deflections and straw-mans that will inevitably be posted in lieu of a logical and rational response to the bolded question:

1) I am not condoning violent protest. I think kneeling for the anthem was a good way to do this. I am addressing the question to the folks that were upset by both kneeling and rioting

2) The anthem kneeling was not directed at the troops. Just because you disagree with the cause/reason, does not mean you get to twist it into a position that is more easy for you to refute. It has been stated multiple times, and from the beginning, the kneeling was directed towards the treatment of black people by law enforcement

3) It doesn't matter whether or not you agree with the core reason that these riots/protests occur, i.e. if you do not believe there exists a cultural problem between blacks and law enforcement. The question is what form of protest would be acceptable, not whether or not you think protest should occur.

This question is geared to those who condemned kneeling and rioting. What should the avenue be?
