She wishes for all men to be imprisoned in Nazi-esque concentration camps, and used exclusively for breeding stock to keep the human race alive.
Downplayed: Alice only brings up her anti-men views when it's appropriate to the conversation, and can interact with non-Straw Misogynist men normally.
Alice is a troll who opposes feminism and purposely tries to annoy men and true feminists with her strawman performances.
Alternatively, Alice had an upbringing in which she was treated horribly by her Straw Misogynist family (even her mother was a Female Misogynist), which made her opinion of men in general very negative.
Alice has been conditioned (either by upbringing or later radicalization) by other Straw Feminists to believe that all men oppress women For the Evulz and/or are literally subhuman and only necessary for reproduction purposes.
Alice's radical ideologies are actually being used to promote feminism.
Bob assumes that Alice is going to be like this upon hearing that she's a feminist, only to learn that she's a moderate.
Alice expresses some pretty hateful views of men... And then goes on to attack her fellow women with equal vitriol, and turns out to just be misanthropic in general.
Then Carol and Dave show up and presented as moderate reasonable feminists in contrast to Alice's extremism and irrationality.
Alice's views are in fact not hateful or unreasonable at all, but everyone perceives her as a man-hater because of the very societal forces she's fighting against.
Alice is a misandrist, but she doesn't identify as a feminist despite what others think. She may even accuse women who don't fit into narrow gender roles of trying to be like men or being men and thus inherently inferior.
Alice only pretends to be a moderate for her own reasons; her views are actually more extreme than she lets on.
But she still thinks men are worse.
That's just a facade they put on to get people on their side. They're really a man-hating prudish lesbian couple.
Zig Zagged: Alice claims to be tolerant but secretly loathes and distrusts men ... hoping that by her actions, men will be spurred to be less lazy, be cleaner, treat women better, or do whatever the story requires, and thus "earn" an equality with women that is societal ("you're not allowed to abuse your spouse") and 'practical' ("wow, honey, thanks for cleaning your stuff, even when I didn't ask").
Alice is presented as a reasonable, intelligent and moderate woman.
Alice is never identified as a feminist.
Alice is used to explore the more extremist and nonsensical ideologies of feminism, but it's made clear that she is not meant to represent feminism as a whole or even the majority of feminists.
Enforced: "Feminists are crazy! How can I lampoon them to best effect?"
Lampshaded: "You'll have to excuse Alice — she's one of those crazy feminists..."
Invoked: "You can't be a feminist without wanting to completely crush all men, honey!"
Exploited: Patriarch Evulz covertly funds Alice's misandric crusade in order to discredit real feminists.
The heroes are in a quest to bring equality to all, and Alice is one of the antagonists (the others being chauvinists and bigots).
Alternatively, Alice is from a place/dimension/era where Straw Feminism is the accepted philosophy, and if anything Alice's views are milder than the general public. She somehow ends up in the modern world however, where her views seem extreme to normal people.
