AITA for refusing to let my autistic BIL meet my daughters?

Protecting children from potential harm is every parent’s top priority, even when it involves family members with disabilities. A 38-year-old woman and her husband of 14 years have two daughters, aged 13 and 9. The husband’s autistic brother, who is severely disabled and cared for by his mother (the mother-in-law), has a history of exposing himself and attempting inappropriate touching in front of the poster. These incidents were dismissed lightly by the MIL, and the brother has been removed from public places for similar actions.

What makes the story more complicated is that the MIL and brother are moving back to town and expect to meet the nieces they’ve never seen. The parents firmly decided against any contact due to safety concerns, leading to outrage from the MIL who accused them of discrimination. The couple stands united in prioritizing their daughters’ well-being over family pressure.

‘AITA for refusing to let my autistic BIL meet my daughters?’

Past encounters with the brother-in-law left lasting discomfort.

The family dynamic shifted with an upcoming move and new expectations.

The confrontation revealed deep disagreements about boundaries and safety.

The parents remain firm despite feeling there are no better options.

This case touches on the difficult intersection of disability, family obligations, and child protection. At its heart, the issue is parental responsibility versus expectations of unconditional family acceptance. The brother-in-law’s severe autism leads to behaviors that would be considered sexual harassment or indecent exposure in any other context, regardless of intent. Parents have every right—and duty—to shield their children from foreseeable risks of trauma.

The MIL’s minimization (“just slap his hand away”) reflects possible caregiver burnout or desensitization, but it does not obligate others to expose minors to the same risks. What adds complexity is society’s tendency to frame such boundaries as discriminatory against disability, when they are truly about safety.

Some argue for supervised, limited contact to maintain family ties, acknowledging the brother’s lack of control while managing risk. Broader social views often pressure families to accommodate disabled relatives at all costs, yet child welfare experts consistently prioritize protection from sexualized behavior, even unintentional. Ultimately, no one is required to sacrifice their children’s emotional safety for inclusivity when past patterns suggest real danger.

Here’s how people reacted to the post:

Many users strongly supported the parents’ decision, stressing child protection above all else.

A few commenters offered more nuanced or cautionary perspectives while still agreeing with the boundary.

Some brought strong emotional reactions or pointed commentary to highlight the seriousness.

The overwhelming consensus is that the parents are not wrong for refusing contact—protecting their daughters from known risks of inappropriate and potentially traumatizing behavior takes precedence, regardless of the brother-in-law’s disability or family ties. The situation sadly illustrates how caregiving can sometimes lead to minimized boundaries, but it doesn’t change a parent’s duty.
