Boomers today would much rather squawk about threatening lawsuits or getting other people to do the work for them. The ones alive today feel confident in their command of the legal system to get what they want. During the 1960s, how many young Boomers and Silent Generation protested against the Civil Rights movement? Literal bombings and terrorism took place. One black family moving into Cicero, IL led to a violent mob of 4,000 people where it was also young Boomers that shouted and held up swastikas and eventually firebombed the building where the family was going to move in, leaving many other residents of the same building out on the street. -- https://allthatsinteresting.com/anti-civil-rights-movement
Yes, there were obviously not the same people protesting against the war in Vietnam. But, to their credit, Boomers used to turn out for protests back when they were 20.
If you asked Boomers this questions when they were 18-25, I expect their opinions would align pretty close to Gen Z in this survey.
