Yes, It’s Allowed to Talk Politics! (But Here's How...)
1. CHECK YOUR NON-VERBAL
Ideally, if you could see your shadow in a mirror during the discussion, that would be great. Not possible? There is another trick: watch your mouth. Are your lips pinched or tight? You exhibit your disagreement and your interlocutor is aware of it. Also, watch your arms: if they are firmly crossed (like "keep talking") then you have to relax!
2. YOUR DISCUSSION PARTNER IS ABSOLUTELY RIGHT
Well, not necessarily, but act as if! What is the point of proving that your partner’s thoughts are wrong (especially if you are right). Yes, it feels good to be told "you're right", but as it’s not going to happen, might as well smile. Do right and fear no man, make it your mantra!
3. SAY "I UNDERSTAND"
You will be amazed by the result. No need to agree, simply to concede "I understand", your interlocutor will now have to deal with your great understanding. This way, the level of decibel remains tolerable and you will avoid insults.
4. WE VS. THEM
To talk politics does not always equal a contradictory debate: one can have a different opinion and be in the same camp. How? By becoming the "We" that discusses vs. the "They" who are the politicians. Ah-ha! You are suddenly on the same side as your interlocutor. Isn’t this beautiful?
Take advantage of this election campaign to practice these infallible tricks. You will reach the elite level in no time, and you can reuse these same tricks later in all the delicate discussions.
