People have more or less completely forgotten that vampires are meant to represent the monstrosity of an unchecked aristocracy/wealthy upper class. They sold their souls for power and now live exclusively by feeding off those beneath them. You don't just 'become' a vampire like you don't just 'become' rich. You can certainly become enthralled to a vampire though

Minus: can't eat garlic.

Jokes on you Anon! If everyone is a vampire then who's blood do you suck?

Anon has not considered the consequences of an entire nation of hungry vampires devoid of humans.

Wasnt there a movie about this where almost everyone was basically a vampire, and started running out of humans and human blood to eat?

Vampire here.

I don't drink blood (because that's disgusting, and also crual and unfair), I drink vaginal juices.

AMA

OP really thinks vampires aren't gay?

Congratulations, you're ageless, will never retire and you have to do a lot of manual labor, as it's cheaper than a machine, if you convert a country. If only a few are converted, others will want to hunt you down and put you on a shelve as trophy.

OP: Killing people isn't a con

Anon might be Dio

Another con is that vampires are even more immortal than they appear. Even if the vampire's body is completely destroyed, their soul will wander through the universe, unable to affect anything, but still conscious. They can't even communicate with other vampires in that state. They'll get to see universe die starting 10 to the power of 16 years from now (end of star formation) until it's finally dead at 10 to the power of 10 to the power of 120, when universe reaches its final energy state. But at least a new universe will start at 10 to the power of 10 to the power of 10 to the power of 56. (https://en.wikipedia.org/wiki/Timeline_of_the_far_future)

Can vampires sustain themselves on alien blood? Just imagining a brood of vampires conquering Earth and then setting their eyes to the galaxy. Like they have vampire scientists who find ways to let them enter sunlight and enjoy Italian food once more.

People suggesting you’d have to kill for blood haven’t seen true blood. IIRC the vampires in that book/show found a way to coexist with humans because human nations created artificial blood (that you could buy like soda at a convenience store etc)

Edit a whole bunch of other stuff happened, but that’s one aspect from that setting

For more about how an empire of vampires would turn out, read “Empire of the Vampire”

Before much longer, no one will be able to go out in daylight.

Can vampires sustain themselves on other vampires blood?
