Equality doesn't mean equal treatmeant, but equal outcomes. Obvious black and white examples like men don't need cervix screening.

There are more nuanced things too, like homeless rates, suicide rates, career opportunities, sexual assault victims, education graduation rates, family court biases etc. All things that require nuanced attention between the sexes, and aren't easy to get right.

99% of feminists are just your every day person, wishing for a more equitable world. There's fringe parties of every socially political movement. I've kind of always wished there was a slightly more balanced name, but the movement started from the suffragettes, so it makes sense from a historical stand point.
