In far too many instances these days, childhood is being turned upside down for school-age kids.

Too many young hearts, minds and souls are being hit with ideology meant to stir confusion and ambiguity — thanks in large part to public schools. It’s alarming at best, and parents need to be alert about this.

Indoctrination — commonly disguised as “anti-bullying campaigns” — is taking place in many, many elementary schools. This is redefining not only curricula but what it actually means to be a little boy or a little girl — or neither, or both.

It’s happening beyond our borders, too.

An elementary school in Canada is the latest place to push an LGBTQ agenda in the Left’s culture wars.

A Brampton, Canada, elementary teacher on April 11 tweeted a poster her third-graders had prepared for kindergartners for the International Day of Pink, LifeSiteNews reported. The Day of Pink, celebrated that same day of April 11, is promoted worldwide as an event against bullying, discrimination, homophobia, transphobia, and transmisogyny. (Did you get all that?)

In reality, it’s an egregious attempt to promote gender confusion, especially among small kids.

“We invite everyone to celebrate diversity by wearing a pink shirt and by organizing activities in their workplaces, schools and communities,” read the Day of Pink website, registered in Ontario, Canada.

What made this incident disturbing is that it appears the teacher, identified as “Mrs. Maciel,” was using her third-grade class as proxies. The poster depicted various cartoon characters plastered to hearts, dancing under the words “Love is Love,” relating that love has no gender, no race, no religion, and no age.

No age? What does that mean? And why on earth would kindergartners be concerned with age?

“This poster is ‘grooming’ elementary school kids to accept all sorts of sexual relationships,” Michelle Cretella, a Florida pediatrician and the president of the American College of Pediatricians told LifeZette via email.

“The cartoon stating ‘Love has no age’ can certainly be interpreted as promoting pedophilia,” she continued. “What is most disturbing is that the third-grade students were solicited by their teacher to create a ‘Love is Love’ poster marketed specifically to kindergarten students. Young children are being used to groom even younger children,” she said.

The cartoon “is a combination of child abuse and cultural Marxism. It’s completely wrong,” Jack Fonseca, senior political strategist for Campaign Life Coalition, told LifeSiteNews.

“It should be illegal to intentionally try to confuse children about the biological facts of human sexuality, that there are only two sexes, male and female,” he added. “Moreover, gender theory — which holds that there are many genders and these do not necessarily correspond to one’s biological sex, but can be changed at will — is not only scientifically wrong, but it has the potential to produce massive sexual confusion in the minds of the young,” he also told LifeSiteNews.
