Protests, riots, and creation of autonomous zones is likely to go one of a few ways:
-induce political discussion
-induce unbecoming discussion that violates other standard policies
-induce speculative discussion of covid in groups, against the covid policy
It is hard to think of a viable topic that would be suitable for any of the sub forums, related to a protest.... even g&ot. I personally do ask a lot of DIY and repair questions in the g&ot forum, so if, say, you had damages to property during rioting, some repair questions might be ok, so long as the context does not create opportunities for discussions that cause the issues highlighted above.
Best to err on the side of caution, realizing that generally protests are political in some way (including protesting against something to advocate for political change) and thus not a desirable topic for BITOG.
