In most Western democracies, many of the key human rights for women have been won - right to vote, education, contraception and abortion, divorce, ability to work and own property and wealth in own name etc.
Yes there's still lots of other issues to be tackled, but the average woman in the UK, for example, can afford not to think much about feminism or women's rights as many of the things women are able to do today have been won through the efforts of women in previous generations and through various technological/medical developments.
It's easy to forget how far women's rights have come, and it's usually presented as something that just happened after some women led a few marches and rallies, rather than explaining how these women had to push for the changes against the odds, being mocked by politicians and society in general, viewed with contempt and framed as unreasonable troublemakers.
I don't think it's unique to feminism. Most of the freedoms and rights we take for granted in Western democracies came about because some people decided to fight for it and challenge the political establishment, sometimes at great personal cost.
You can see it these days as many people don't seem to cherish things like free speech and think it's ok to censor or shut down views they don't like or they feel is offensive, without realising that a few decades or centuries ago their own views would have been viewed as grossly offensive by the majority and would have led to persecution or harassment.
