Ignorant abuse and smirky loutishness are indicators of intelligent dialog. The Ukraine posts are classic examples of this. A cadre of loud mouthed fools and paid trolls dominate the posts making intelligent dialog impossible.
Making intelligent dialog impossible is with just about every topic here... Just look at the posts about history or archaeology. It is impossible to have any intelligent dialog because of the purposeful distraction and disruption from the class clowns hell bent on derailing the thread and any productive discussion.
