Forgetting that yes, this is America, and that therefore people are free to fly whatever flag they want to in their own yard, an Ontario, California woman went on a tear that went viral and cost her the job she held at a real estate company.

Tressy Capps, who seems wound a bit tight, filmed herself harassing a homeowner over a flag they were flying in their own yard.

She berated the homeowner, suggesting the residents of the home go back to Mexico.

It wasn't a pretty scene. 

She filmed herself on her smartphone, and then proudly published the video to YouTube. 

The video has more than 136,000 views as of the afternoon of Sept. 26.

But the story didn't end there.

CBS Los Angeles had the story.

A controversy involving the Mexican flag has one family in Ontario wondering why one woman made it her business, while the people she did business with, in turn, asked her to leave.

Tressy Capps, a local political activist in the Inland Empire, was irked by seeing the Mexican flag flying in a front yard and confronted the homeowner on a video she shot on a smartphone and posted to YouTube.

“Hi. Is that a Mexican flag in your front yard?” Capps is heard asking the homeowner, who is behind a window.

“You know we live in America right? This is the United States. So, why are you flying a Mexican flag in your front yard?” she is heard asking the woman.

Here’s the news video:

And here’s the original video that Capps shot and uploaded to YouTube.
