"We poison our air and water to weed out the weak! We set off fission bombs in our only biosphere! We nailed our God to a stick! Don't fuck with the human race!"
How to make environmentalists cry and feel good about it.
Out of all threads that appear at the /tg/, it is this kind of threads that hold that one special place in the hearts of fa/tg/uys. It shows humanity for what it really is: a savage bunch of hairless apes with machines that rape the planet, leave it drained and dead, so it could just move to rape other planets as well.
Many glorious hours of dedicated hard work were given to these threads, making some of the finest lines which would make any xeno race run to the edge of the known universe, even if said xeno race was still in the stone age. Reasons why humans are such a threat to the rest of the galaxy are various, but a good deal can be summed up in the following list:
- Our evolution - We evolved and THRIVED in the African savannah, a place where everything is trying to KILL YOU! ALL THE TIME! Aliens usually evolved on some herbivore world or become less "on their guard" due to centuries of living away from nature, not troubled by survival.
- Our history - Humans have been getting better at killing each other basically even before they made stone axes, and we got better over time. You think proud warrior races have shit on us? Spartan style training they undergo makes only a handful of survivors. No matter how good they are, we'll just drown them in conscripts.
- Our bodies - Some of us can take an amount of drugs and booze, which is POISON, that would probably kill a decently sized buffalo herd.
- Our mind -The most terrifying aspect of us would probably be our brains and technology. Our aggressive instincts combined with our intelligence will never cease to come up with better and deadlier ways to torture and exterminate the enemy, and such would proobably seem like incomprehensible Lovecraftian Magic to lower species. Our modern tech would scare the shit out of tribal communities. We have exterminated a lot of species like the Dodo simply by uncaring accident. What we can come up with scares the shit out of ourselves even. Think Nuclear Weapons and M.A.D. for example. What reasonable mind would, on any other planet in the galaxy, EVEN THINK that having enough nuclear firepower to destroy your only planet twenty times over, would be a guarantee of peace?
As you can see there is a lot of material to roll around in these kind of threads. Humans may not be as powerful sometimes, just a serious player in the galaxy through economic superiority or science, but that's not the real "Humanity Fuck Yeah" thread. The real deal is us having our way with the galaxy as we see fit. Murdering billions of xenos, taking their delicious alien babies and eating them in front of their parents, mining their planets to the core and moving on, leaving nothing but dead rocks in our wake. We march on, our mantra singing through the stars:
GENOCIDE! MINING! GENOCIDE! MINING! GENOCIDE! MINING!
 HFY Summed Up in One Quote
Taken from Warhammer 40,000 Imperial Armour, Volume 12, The Fall of Orpheus.
"Do they not know who we are, my brethren? We are the chosen of the Emperor, the scions of Terra. We are dominion and we are numberless. We are war itself and the death of all who oppose us. We are Humanity and we shall educate our ignorant foes as to the true meaning of that word!" --Lord Inquisitor Aedrick Mantel of the Ordo Xenos
Unfortunately, humans lost miserably in that war, just like in every war against xenos in Imperial Armor series, but at the scale of entire fucking sector.
Sometimes "Humanity Fuck Yeah" always refers exclusively to omnicidal maniac-level racism against everything that isn't non-powered and normal human beings (as people too often don't consider anything super-powered or non-normal as people/"human").
Readers may experience ocular bleeding due to excessive TVTropesisms escaping from humanity's natural habitats. This is a normal, if unpleasant side-effect.
Some great examples of "Humanity Fuck Yeah":

The banner is from Star Trek, but it gives you the basic idea.
Fine example of how we at HFY think.

Technology "saves" the day.
Terra is a cruel matriarch. But her forge has made us strong.
These is what we do to OUR home. Think your planet will fare any better, xeno?
