I think it is telling that the vast majority of people on this thread who are calling the female protesters "infantile" and "shrieking" are male.
It is also telling that every Republican member of the Senate intelligence committee was male.
The Trump-restricted incomplete and inadequate investigation, the attempts to rush the Kavanaugh nomination through with only 7% of the documents provided and inadequate time to look at the FBI report, was clear evidence of a patriarchal system at work, closing ranks to protect one of their own.
About the only "infantile" behavior I saw exhibited in this nomination was the yearbook comments and notes about Kavanaugh's high school days, his letter about renting the beach house, his 36 comments that he liked beer during the hearing, his throwing questions back at Amy Klobuchar (another example of patriarchical behavior), and his ranting criticism of the Democrats and the Clintons.
