Thoughts after watching Billy Lynn's Long Halftime Walk

I am trying to improve my writing skills, I hope that somebody helps me correct this article. Thanks.
Finally, last night I watched this film, unfortunately I could not go to the cinema to see  the 120 frames version. I believe this movie has a charm,  it makes me feel sad, but not sorrowful after watching it. Unlike other movies there is no relief, I just can’t let it go. I feel that somebody threw a stone to my heart and the stone keeps sinking. Our society will eventually run towards the inconceivable future, and we can do nothing about this.
I like to write options anonymously in Zhihu (the Chinese version of Quora), especially when facing a controversial topic. I am afraid of endless arguing, I am not that kind of “smart” guy, I can not write thousands of words to fight back like some famous users in ZhiHu.
Every time when I write something, no matter what it is, there will be lots of people who disagree with me and leave evil comments under the article. They can catch every uncertainty “loophole” in your article and slam you.
This is the war of language; absurd, isn’t it?
I don’t know if other people feel like me, sometimes I think that human beings will finally go to war or worse maybe end our world. I can remember, when I was in high school, the most popular idea was that our world was flat. At that time in China, everything was under inflated. We had tasted the sweetness of reform and opening-up. Everyone was talking about globalization, and how the future will benefit from this. I thought after this we would go to Pax Romana.
However, de-globalization came,  and more and more terrorism around the world.
One of our feet is already wet.
A few days ago, the Australia Senate refused the request for a plebiscite for same-sex marriage. Unluckily, Australia will host a postal vote on same-sex marriage which will cost millions of dollars. Just this morning one headline came to my eye, Sugar Baby (Turnbull’s Chinese direct translation) says Australia would come to the aid of the US if North Korea starts an attack against the western powers.
The politician doesn’t want two people who love each other to get married, but they can easily start a war. Another absurdity.
Once in English class, we were talking about politics, I asked my teacher if Australia's prime minister had passed a new rule that people really don’t like, is there any method to stop it? She thought for a while and said, “Maybe not.”
Maybe not, that is our fate.
