How are the words counted at the writing part of Ielts or Cambridge exams? Do they count prepositions and articles as well?

I need new ideas I really wanted to add another essay to my notebook, but I don't know what I could write more about this subject "Violence is the last refugee of the incompetent".
That's what I've written so far:

I consider that even though violence has many forms, it defines those who don´t know or were incapable to defend themselves or to express their feelings in a smarter and healthy way or manner. It´s their last refuge, because they couldn´t convince or accept others views. Therefore, they resort to violence, because they can´t find a way to make themselves remarcable among others.

On the first hand,   being violent means that you already failed in socializing. You´re not helping anyone, nor even yourself when your last weapon is violence.

On the other hand, let´t take as an example Hitler. Because he coudn´t impose his beliefs, he chose violence to show himself that he´s right and that he has to do that. Everyone feared him and that is the way  he used to achive his political goals.

Hi guys! I'm looking for a language partner. I've been studying English for a while and I find it difficult speaking it, that's why I'm looking for a language partner. You can be a native or non-native speaker as long as you're speaking English pretty well.
I'm learning for an English exam, so if you're studying for Ielts, then maybe we can do it together. [emoji]
