Answer:
To avoid heated arguments about politics it is very important to show respect to the other person. If you are talking about politics and the other person senses that you don't care about them or you are mocking them, the conversation can very quickly turn sour. Also when discussing politics with another, never attack them personally. Even though you might begin to feel a rush of annoyance or anger, never insult him/her. This not only shows weakness on your part, but also insulting the other person makes the less likely to listen to your logical arguments. So if you attack a person emotionally in a discussion ,they will most likely attack you emotionally and personally, thus spiraling into a heated argument. This also shows immaturity and a lack of cool headedness on your part if you cannot discuss a matter with out brining personal issues into the debate. Another way to teach people about politics and lead them towards truth is to try and agree with them as much as possible. Making him/her feel welcome and listened to will "warm them up" to your side of the debate and make them more willing to listen and even maybe change their view on the current issue. But most importantly, show them you care and you are discussing the issue because you care about the other person. It is not wise to go into a political debate with a complete stranger on the internet because the in most cases the only thing that will happen is either persons getting frustrated, angry, and even more at odds with your view than before.
