Over 200 protesters, including some Chinese parents, protested on Wednesday in Toronto, Canada against a revised sex education curriculum in the province of Ontario, which will be implemented this September.

It is "too early and too much" for elementary students to learn about body parts, oral and anal sex, and homosexuality, the protesters said.

Earlier this week, Ontario Premier Kathleen Wynne, the first lesbian premier in the country, announced the unveiling of the first update of the provincial sex education curriculum since 1998, an effort to move sex education into the digital age with discussions of sexting (sex texting) and the dangers of sharing intimate images online.

In a minus 20 degree Celsius temperature, the parents denounced the new sex education in Toronto's Queen's Park, the site of Ontario Legislative Assembly, calling on teachers to "Teach mathematics, NOT masturbation."

The revised curriculum was deemed by many parents as indecent and pornographic and to incite already hormonal children into acts of perversity and lewdness.

London-area MPP Monte McNaughton attacked the curriculum. "This government is disrespecting parents," he told reporters.

Many Chinese parents considered this long-awaited update to be a scarlet letter of smut and that the material is inappropriate for their nine-year-old children.

Tan Guocheng with York Region District School Board said "Parents generally believe this information should wait until the students enter high school in the ninth grade. At 14-year-old they can have a talk about sex education and the sex education curriculum."

The Chinese parents believe that the new sex education curriculum will teach children too early a variety of sexual behavior as a whole that leads to HIV infection.

About 10 young people stood supporting the new version of the sex education curriculum, citing students should learn gay issues to avoid discrimination against homosexual students and reduce the rate of gay student suicides.
