Woahh! I can't believe there is some people that really believe that explanation! This is a comic for god's sake everything is to take with second degree!
But let's get some facts right:

1- Toxoplasma gondii is a parasite adapted to cats and rats. They are not adapted to humans and we are just accidental hosts. Does it influences rat's behavior? Yes, because Toxoplasma adapted in such a way so that it can end his cycle in the cat (which is the definitive host).
2- Toxoplasma is a parasite found worldwide. Around 50% of the world population is or was infected at some point.
3- In humans, toxoplasma produce symptoms of mild cold, usually we don't even realize we were infected. Where it is dangerous is for pregnant women, because the parasite affect the foetus. But that's only if the woman doesn't possess an inmunity against it, meaning that she has never been in contact with the parasite at some point on her life. Otherwise our body can easily fight it. That's why they say that pregnant women should be careful with cats.
4- Prevalence means you possess INMUNITY against the parasite. It doesn't mean necesarly you have the parasite right now, just that you were infected at some point in you life and you developped an inmunity. When they say 84% is infected, you are talking about the prevalence and it means that 84% of the population was infected at some point in their life and have inmunity.
5- Prevalence is high in countries where people lives a lot with cats. Prevalence is high in UK, Spain, Germany, France, etc...
6- Personally I don't think that French are more agressive driving than any other country (except those who live in Paris, but Paris is like another world for French xD), you should go to Roma one day...
7- Recent studies demonstraded..... nothing. Really, right now the studies doesn't have any relevant information and don't have any definitive conclusion.

Otherwise nice comic as always!
