Thought Experiments 2 and 3

I'm going a different route for Thought experiment 2 and 3. for the first one, I wrote mostly about man's unhealthy parasitic relationship with technology and its effect on the loss of humanity and devastation of the planet. I used this essay as a launching point for these next two thought experiments.
TE 2 & 3: What if an alien parasite crash landed on earth and began repopulating. unlike many movies and books, where the alien is a "bad" guy, my TE3 shows the cold hard logic of th landing parasite. My parasite resembles the ones from The Faculty, but the story is approached differently. The invasion happens easily. In a discussion in The Faculty, Casey, Elijah Wood, rants along about: what if all those Hollywood sci-fi moves were just a warning from good aliens, trying to prepare humans for an eventual attack...well, I thought a more realistic way of taking this would be, What better way to make people not fight an alien attack? Do you take fiction movies, especially sci-fi movies, as potential manuals on what to do if our planet is attacked. NO. you watch a fiction movie, and now it will never happen. it couldn't, a sci-fi movie just did it. In fact, I believe if we were attacked by a parasite that makes everyone a little off and the news made fun of it and no one really discussed it, the alien would take over, with little to no trouble at all. In fact i know this. If an invading parasite started taking over. TV would take it half stride. People would laugh it off until it was at their front door, and by this time, still barely not believing it, it would be too late to fight anyways. Fiction destroys credibility for completely possible things.
The other idea i play with in TE2, is the idea of a non-lethal and not necessarily negative parasite invasion. The parasite takes away complex human feeling, with it all discrimination, hate, love, anger, everything. I really pull the reader though ideas of freewill vs. world peace. As, the parasite's refuse to harm their own species. War ends. Also, the planet is preserved, as the parasites refuse to use more than can be restored. they see it as more practice to live humble and practically now than to squander it all in fits of greed and have nothing down the road. the other thing the parasite's do to their hosts is keep it nice and fit. They keep it in shape, they eat well for it. They just stay in the body for nutrients and to reproduce, oh yeah, and the person you knew, they are gone.
"Would you surrender all feelings of hate, if love went with it?"
TE3...while maybe I should wait to get my grade back from TE2 before i start on part 2, I'm going to have to just run with it anyways. This one is done from the point of view of one of the last surviving humans. This one is really going to ask the reader: are things just wrong? Over and over again in different ways. The main character, the son of the first infected person in the first part, is a human rights activist. one of the few, as their are less than a million people left in the world at this point. he was once a typical lefty activist, fighting for peace, freedom, and stability with mother earth. Now faced with literal peace on earth, a non selfish economy, and a system that favors mother earth, he finds that he would much rather defend freedom at all costs, even if it means we destroy the planet, zone out on tv sets, and hurt each other. The antiheroes are void of any dignity though out the story, as they march around in helmets and chastity belts and get stared at everywhere they go, because the parasites know who isn't infected. while the hunt for remaining humans is deemed pointless by the worm infested whitehouse, the main character has his mind set on winning an impossible battle to reclaim humanity, faults and all. His labors prove fruitless, I'll tell you now. Less than a million people against all the armies and people of the world, yeah right. But maybe there is hope, maybe their is some main parasite, that once killed would make everyone go back to normal? wait, that would be stupid. if there was, it would either be impossible to reach or on another planet.
