I don't personally see a clear connection between the two events, but Bob Fogel had an idea about this. I'll present it without endorsement.

Women generally prefer somewhat older men, and men somewhat younger women. As such, with the Baby Boom generation being so large compared to the Silent Generation, the dating market was rather favorable to Silent Generation men and unfavorable to Boomer women. This lead, in general, to men acting somewhat caddish and inconsiderate. This, in turn, lead to discontented Boomer women embracing feminism.

Now, personally, I don't find the Fogel theory all that plausible. For one thing, lots of women being at a power disadvantage leads to a lot of female empowerment in reaction? You can tell a story in which that happens, but it seems like you could tell almost any number of alternative stories -- most obviously, that some group being disempowered leads to them being, well, disempowered. No doubt if women had reacted to the poor dating market by becoming more feminine, submissive to men, and generally competed for the smaller pool of Silent Generation men through traditional femininity and rejection of feminism, a post-hoc story similar to Fogel's in its Silent Generation men/Baby Boomer women dynamics would be easy to tell.
