Sometimes this is logical, other times it seems like an attention grab. It is fairly common for certain communities on, for example, Livejournal to be overly sensitive to people's 'triggers' (often but not always relating to sexual assault)--any mention of violence may be censored.
Why having kids later is a really big deal. The average age of American women having their first child reached a record high of 26 years old in 2013, according to the Centers for Disease Control and Prevention's National Vital Statistics Report.
Overall, Americans tend to believe the ideal age to have one's first child is a bit younger for women than it is for men. That likely reflects the greater relevance of women's biological clock when it comes to childbearing. However, on average, the mid-20s is seen as the ideal age for both genders.
