We know know how rabies works. An infected animal becomes more aggressive prior to death. It will end up biting other animals to spread the infection along.
This is an example of a behavior-modifying organism.

What you probably don't know is that there are hundreds of other organisms that also affect behavior. A virus causes caterpillars to climb up trees. Then it
liquifies their organs so the body disintegrates and the virus can be spread by the wind1. There is a STD for grasshoppers that makes them more sexually
active2. In the days prior to experiencing the symptoms of the flu, the virus will make you more sociable so can transmit it more3.

Here's the real kicker though: There is a parasite that has the ability to modify sexual preference. Toxoplasma gondii. You've probably heard of T. gondii as the
amoeba that infects cats. There's a lot more to it than that. Rats are a carrier of T. gondii. When infected a rat will be attracted to cat urine, making it more likely
to be eaten by a cat, the intended host. How does it work?

>Toxoplasma alters the brain to make the rat sexually attracted to cat urine4.
>Toxoplasma’s ability to make rats sexually attracted persists even after the rat is no longer infected4.1.

That's right- a parasite has the ability to PERMANENTLY ALTER SEXUAL PREFERENCE in its host. Dig deeper into the facts behind T. gondii and we see:to create
sexual attraction to men. You've probably heard the false "genetic hypothesis" that claims that female siblings of gay men have more babies, meaning that gayness must be an advantage. Well the
"gay gene" has been disproven but toxoplasma explains why the sisters are having more babies. The same toxoplasma that altered their brother's brain altered their brain to increase their sexual
attraction to men. Homosexual men are having more sex than their heterosexual counterparts, spreading toxoplasma further. Use HIV as a proxy for how effective homosexual behavior is at
transmitting disease: homosexuals are 10% of the population but account for 60% of new HIV cases.In response to homosexuality- homosexual disgust aka "homophobia" has evolved as a means to avoid toxoplasma infection. The purpose of disgust is disease avoidance10. You are disgusted at the
sight of feces because feces has a lot of bacteria. You didn't need to learn to avoid feces; it's just genetic. Similarly, homophobia was found to be genetic, and also present in nearly half the
population11. This means that homophobia evolved because it increases your darwinian fitness by helping you avoid toxoplasma.
