A third of the entire human population is infected with toxoplasmosis, in some places nearly every human.

If you put humans in a sterile bubble you get a different set of diseases, to a considerably greater degree because your immune system evolved in an environment where you actually got infections.

By that logic, we shouldn't be fighting malaria in Africa either.

Are there any benefits to toxoplasmosis besides some people finding the vector cute? The alternative isn't living in a sterile bubble.

		Without infections your immune system gets bored and starts attacking you. You need to have something for your immune system to do on a regular basis. Toxo is to a very large degree asymptomatic. You are full of and covered with organisms. Being paranoid about infection isn't helpful to anyone. Ok you don't like cats, that's fine, but are you as passionate about rare steak which is a much more common vector? Malaria... is not asymptomatic.
