There’s trouble brewing at Starbucks, and if you believe what you read on social media its 2015 Red Holiday Cups are the greatest threat to Christianity since the Islamic State started beheading the faithful.

A very vocal group of Christian coffee lovers is a bit perturbed at the lack of yuletide flavor in their 2015 Red Holiday Cups.

Previous designs have included all sorts of Yuletide accessories from scarves to ornaments to snowflakes.

But this year Starbucks decided to go minimalistic. It’s just a plain red cup — no holiday messages, no holiday images.

And that has folks accusing the coffee giant of being anti-Christmas.

“It’s not just about a cup,” said Arizona-based evangelist Joshua Feuerstein in a message to The Washington Post. “The cup is symbolic of a larger war against Christianity in this country.”

Feuerstein let loose on Starbucks in a now-viral Facebook posting.

“Starbucks REMOVED CHRISTMAS from their cups because they hate Jesus,” he said.

To be honest with you, I’d be willing to wager a fruit cake that Starbucks doesn’t have any idea who the reason for the season is in the first place.

“Do you realize that Starbucks wanted to take Christ and Christmas off their brand new cups?” he said. “That’s why they’re just plain red.”

Not true, says Starbucks.

They said they just wanted to create a culture of inclusion and diversity.

“This year’s design is another way Starbucks is inviting customers to create their own stories with a red cup that mimics a blank canvas,” the company said in a statement.

Whatever.

I mean, really. All of this outrage over a coffee cup?

It’s not the Holy Grail, folks. It’s a cranberry-colored, environmentally friendly coffee cup.

I stopped drinking Starbucks coffee years ago back when its chief executive officer said he did not want to do business with people like me — a gun-toting, Bible-believing offspring of white privilege.

So I figured, why spend my hard-earned money on a company that actively opposes my values?

I’ll probably be fielding some angry emails about my take on the Starbucks controversy — but should we really expect a secular company to embrace Christianity?

It wasn’t too long ago that many of the same folks complaining about Starbucks were defending Christian-owned bakeries and flower shops.

The way I see it, we ought not to be telling bakeries and florists how to run their business and we ought not to be telling Starbucks how to run theirs.

It’s really disappointing that folks don’t get their lattes frothed over more pressing matters — like the mass extermination of Christians in the Middle East or the raging war on religious liberty here in this country.
