Obama uses a communication technique called Neuro Linguistic Programming (NLP.) The idea is that the words being used are simply a vehicle to implant an underlying message.
For example, when he says that “the parents of Sandy Hook deserve a vote” on gun confiscation – the underlying message is that gun owners are aiding and abetting child killers. When he says that “all scientists agree that CO2 caused Sandy” the underlying message is that climate skeptics are planet killers.
I have had experience dealing with an NLP trained adversary, and it is simple to shut their BS down. You have to argue against their message, not their words.
For example – you say “Everyone wants to protect children, and your attempt to conflate legal gun owners with psychotic murderers is disgusting and unacceptable. Sandy Hook parents deserve a constructive discussion about how to prevent violent crime, not a knee-jerk destruction of the Bill of Rights”
You can also say “Hurricanes, floods and droughts have plagued man since the dawn of history. Blaming your political opponents for the weather is the worst kind of McCarthyism.”
NLP only works on people who have been trained to politely accept blame. Don’t be a victim. If you respond to their message, rather than their words – the NLP aggressor gets confused and disoriented because their plan failed.
