I haven't posted about neither as I'm not too familiar or informed enough to post about them. Sure I have my opinions but on Hive I try to support users based on them, not based on where they are from or their political or humanitarian opinions. You'd be better off being loud towards users who may actively post and comment about such topics is all I'm saying.
Or just being more active yourself to spread the word rather than assuming people don't post about something because of some unspoken rules.
