He literally doesn't tho.
Bro thinks the word "notion" is a synonym to the word "term."
No. I use it in the meaning of the word : As a knowledge or rather the observation that all people have political vectors.
This is a neologism based on a real observation : People radicalize all the time through pressure and experience
For example my vector since 2020 ishg has been aimed toward the far left and hardcore materialistic belief systems. This is something that I know even if I'm not a far leftist but only a radical one, this means that if I keep amassing experiences without big contradictory knowledge for my current ones, I will become a far leftist at the end of the day. But it wasn't always the case, a decade ago, my vector was aimed toward the far right.
I think that depending on people, the vector will vary and the force applied toward radicalism also. For example, I could say that Biden's vector is aimed toward the left but with a very weak strenght. On the other hand, Harris's vector toward the left is a LITTLE bit stronger (but not enough).. this can be said because
Trump, for example, has a big vector toward far right ideas. Meaning that if he doesn't meet contradictory knowledge or experience, he will dive deeper and deeper into the alt-right.
Progressism and conservatism are what I would call those vector. Depending on a situation you can be a communist and be a complete conservative. Depending on the direction, you will be more likely to adopt more conservative (toward the right) or more progressist (toward the left) ideas.
Authoritarism and dictatorship will happen when we allow someone who has a conservative vector and an immense force to rule on side or the other.
No one is neutral in politic. Meaning that everyone evolves constantly.
So the good question is : What is your vector and what is it's strenght ?
And from this question, discussions can become very interesting.
I have never seen someone change the definitions of words more.
Fun fact. I never change definitions. But I tend to create new ones to extend the lack of previous ones (or the ones that I simply do not know about : For ex. My concept of political vector could be something that is already existing, but I simply don't know the name)
For the most part, I use what you can find in any encyclopedia or scientific papers or activist database.
But yeah. I tend to be cautious of dictionnaries. For me, they are not viable sources of information in a world where language evolves and where language can become a battle for legitimacy.
Do not be afraid of people who give you a new definition for non scientific language. It's usually a sign that you are seeing a new perspective. Be cautious, we never know, but take it seriously.
