WATCH Tucker Carlson’s head explode when expert tells him the CAUSE of the trans boom. (Hint: It all started with Obama.)

While leftists love to argue that transgenderism has been around since the dawn of man, the truth is, it’s a new concept – a very new concept that's gained incredible momentum over the last decade.

Many wonder where the trans boom originated and why it’s become so trendy in recent years.

Well, looks like we may just have an answer.

Dave Rubin plays a clip of a recent episode of “Tucker on X” in which the former Fox News anchor met with policy expert and documentarian Chris Moritz to discuss this very subject.

“In terms of the pace of growth for, let's say, clinics serving pediatric patients on gender issues, in the last 15 years in the United States, we had zero now to over a 100 clinics for kids,” he told Tucker.

“Why?” asked Tucker, whose brow furrowed in growing concern.

“It’s a very complicated question,” answered Chris, “and there's a lot of different reasons why.”

“I would say that the biggest single policy catalyst for this explosion is Obamacare. When ObamaCare was enacted in 2010,” a provision was “very quietly … written into the law,” Chris explained.

Due to this fine-print policy, “insurance companies were mandated to provide coverage for what is deemed to be medically necessary gender affirming care,” and “as a result of that, between 2010 and 2016, there was a 50% increase in sex reassignment surgeries, a 25% increase in insurance coverage for transgender individuals, and then at the very end of the Obama administration … an additional amendment to the Affordable Care Act was made whereby gender identity could no longer be a basis for denial of coverage by private insurance companies.”

“As a result of that, the next year from 2016 to 2017, there was a 150% increase in sex reassignment surgeries in the United States.”

At this, Tucker’s expression goes from deeply concerned to downright horrified. To hear their conversation, watch the clip below.
