Members of a popular internet forum were quick to show support for one parent who explained why they refuse to "cater" to their sister-in-law's strict religious beliefs.

In a viral Reddit post published on r/AmITheA**hole, Redditor u/dinokidsaita (otherwise referred to as the original poster, or OP) said that their brother married a woman from a "very religious background," and explained that the couple is raising their three children "the same way."

Titled, "[Am I the a**hole] for telling my brother and SIL that I will not cater to their beliefs regarding their kids," the viral post has received more than 14,000 votes and 2,200 comments in the last 6 hours.

Beginning with the explanation that they are "fairly agnostic," the original poster said there have been awkward moments at family gatherings because of religious differences (not saying a prayer before meals, not going to church on Sunday, etc.), but assured that they have always been handled in a cordial manner.

But after their brother and sister-in-law requested that the original poster and their husband watch their children for a weekend, those awkward instances boiled over into a larger argument.

"My bro and SIL asked if we would be willing to watch their kids for a weekend in April so that they could go on a long weekend trip," they wrote. "My husband and I agreed and they thanked us and we all agreed we would discuss details later."

"SIL sent an email a couple days ago...she outlined what time they would be dropping the kids off, their itinerary and contact info, when they expected to be back, etc.," they continued. "But it also had an odd 'request.'"

"She asked that we remove all dinosaur toys (because in her religion they believe dinosaurs didn't exist)," they added. "My oldest has a lot of them and last time they were over it led to a lot of questions from her kids."

Responding to their sister-in-law's email, the original poster said she was adamant she would not remove her child's dinosaur toys, and reiterated that message to her brother in a later phone call.

"I told her that I don't care about her religious beliefs, but in my home the Earth is round, the sky is blue and dinosaurs existed," they wrote. "I told her if that makes her uncomfortable...she is free to find other options for watching her kids."

"Later that night, my brother called me and brought it up again," they added. "I told him that I am not going to cater to his wife's religious beliefs...and they don't get to dictate the terms of what goes on in our house."

Last December, the Pew Research Center reported that approximately 30 percent of adults in the United States are religiously unaffiliated, a 13 percent jump since 2007.

However, for roughly 70 percent of U.S. adults, religion remains a large part of life, as well as an important factor in many platonic, romantic, and familial relationship dynamics.

Disagreements about religion are one of the five most-common catalysts for feuds among family members, according to Family Education, an online resource for parenting advice.

Although Family Education recommends a myriad of strategies, including open dialogue and the willingness to compromise, for families experiencing tension as a result of differing religions and beliefs, some circumstances prove much more intense than others.

In the case of their sister-in-law's request to remove all dinosaur-related toys and items from their home to avoid questions from her kids, the original poster stood firm in their decision to adhere to their own household values, sparking a sea of comments from Redditors responding to their viral post.

"I was expecting a 'she asked me to let the kids say grace or pray before their meal,' but not a 'I don't believe in dinosaurs so you need to make them disappear,'" Redditor u/Primary-Criticism929 wrote in a comment which has received more than 5,000 votes.

"Their eldest is 6," they continued. "Isn't that kid going to school?"

"That's a pretty fragile belief system if it can be brought down by a toy brontosaurus," Redditor u/TailorVegetable4705 added.

Redditor u/mdthomas, whose comment has received nearly 1,000 votes, said that the presence of toy dinosaurs is not a religious statement, and that OP's sister-in-law should answer their children's questions, instead of avoiding them.

"You're not forcing the toys on the kids, they are merely present," they wrote.

"It's inconvenient that the kids have questions?," they continued. "Kids have questions about everything! If their belief in their faith is so strong, they should be able to handle it being questioned."
