Let's start with pic related. This scared the shit out of me.

Come on, people there would not be able to discuss this sort of thing. They're all enthusiasts freaks. I need unbiased opinion on what's written in that pic, that you probably didn't read at all.

I think that, if we were to encounter a hostile alien race, we would win.

We're very dangerous to our enemies.

>"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!"
badfuckingass.
Civilizations far more developed than us probably have epic biotech and bot engineering.
So, I think what we get first-contact with would be their scouting system or some other AI that isn't one of themselves.
I love atmosphere of alien-related urban legends of the US though.
Extinction isn't that much of a worry to me tbqh. As long as we go out fighting, that's all I can ask for.

Hell yeah.

Fuck yeah. See, Brazilbro? Humanity, especially Americans, will not be beaten down by some pussy aliens.

Oi OP, have you read Blindsight by Peter Watts?
To me, it seemed like a pretty nice book about meeting alien lifeforms, though it wasn't exactly as gloomy as the scenario in your pic, and it touched other subjects as well (mainly neuroanatomy and stuff)
Book can be read free of charge from the writer's webpage: http://www.rifters.com/real/Blindsight.htm
As for your question about meetings with aliens, I'd say that there is no reason to panic. Either everything goes peachy or we have no chances at all.
I say this since it's highly probable that there is a huge technology gap between us and the other possible aliens. Either we are tens to hundreds of thousands of years better than them (our cultural evolution has lasted for only about 10 000 years, after all), or they are.
If we are the more advanced civilization, then fine: no holocaust for us. We'll be happily exploring our neighbourhood with telescopes and such, and perhaps at some point with lightweight Neumann probes. Perhaps even some colonies using Neumann probes as seeds and and sending the information for the colony (how to make buildings, people(?), other stuff) as information, perhaps using high-energy lasers. However, I highly doubt there will be any big mass transfer between solar systems; it's just too costly without star trek/star wars-tier tech. Perhaps kinetic projectiles like your pic proposed will become "economical" (as in it takes one solar system's civilization's entire energy throughput for years to shoot, just to destroy a colony of a inferior civilization lightyears away. Kinda like the USA is using their multi-million bombs against ISIS and their cheap equipment). Radio comms would be the likely way of "meeting".
If we are the inferior civilization, then we have no reason to worry. Either we can't destroy the other civilization and they won't retaliate because of that, or we'll be wiped away before we even know it. I say there are bigger risks for us, like our own actions.

Thanks for taking time with that great reply. I'll read the book.

Lol. /tg/ grognards are adorable with their asinine 12 year old power fantasies and lack of applicable understanding of actual military or scientific capabilities of a first contact scenario.
I wonder how it really would turn out if we met a hostile species an order of magnitude more capable of destruction than us. But it probably won't end with will smith punching one out.
>>52827810
Dude, i know that we would be wiped out within seconds if an advanced alien species wants to.

You are the one calling him a jew.
