What is one fourth grader's argument for marriage equality? Essentially, "Get over it."

When the fourth grader's teacher posted a photo of the essay on Reddit, a social news site where registered users can post content, Wednesday, it quickly took off.

"One of my fourth grade students chose gay marriage as his topic for a persuasive essay," the teacher, Reddit user rafa3l2, wrote. "This is the result. More sense than some adults."

The student wrote:

"Why gay people should be able to get married is you can't stop two adult's from getting married because there grown and it doesn't matter if it creeps you out just get over it. And you should be happy for them because it's a big moment in their life. When I went to my grandparents wedding it was the happies moment."

"I am not sharing this because of how perfect the sentences are, but because of how clear his thought process is on this specific issue," the teacher wrote on Reddit. "It isn't as simple as pointing out mistakes and spelling errors."

The essay, errors and all, has since been posted on Huffington Post, Buzzfeed, Towleroad, and shared on social media sites, such as Tumblr.

Other recent letters and emails have also hit emotional notes and gone viral.

Last month, a young girl's letter to Yosemite National Park also touched hearts when a park ranger posted an image of the letter on Reddit, noting the girl's admirable attempt to return two sticks she had accidentally taken from the park.

While the fourth grade writer's essay might not change any laws, GLAAD, an organization that supports equality for lesbian, gay, bisexual and transgender people, fully endorses the student's efforts.

"This fourth grader is echoing what a majority of Americans of all ages now feel, and perfectly represents the respect for diversity that this student's generation is learning," Wilson Cruz, a GLAAD spokesperson, told ABCNews.com.

"This student is absolutely correct in saying that marriage is a 'big moment' for a couple, and creates a sturdy foundation for the rest of their lives.

"Children are wiser than we often give them credit for."
