Never feed the trolls. It only encourages them. Logic truth and fact are only tools to them, when they have no fact or logic on their side, they use lies and invective. Never answer their posts, and they go away.
"You cannot help the poor by destroying the rich. You cannot
strengthen the weak by weakening the strong. You cannot bring on
prosperity by discouraging thrift. You cannot lift the wage earner
up by pulling the wage payer down." Abraham Lincoln
