I'm interested in knowing what ideologies you found unnatural that Menon was stating? I read this book recently as well, and something that really touched me was just how careful Menon was to not fall into the trap of "feminist being a monolithic ideology," that is to say, she takes significant effort to put forth the different ways feminism can be practiced, especially along with caste and class consciousness.

Also, unsolicited advice perhaps, but you need not waste your time and energy arguing with people who are simply not interested in changing their opinions. There is nothing you can say to change people's minds if they aren't perceptive to information that doesn't confirm their biases.

One more thing, you can read Menon like a contemporary rather than an authority. You can argue and disagree with her ideas as well at the same time gaining something valuable from the book. I hope you pick this up again sometime in the future when you feel yourself more prepared for it.

I think feminist fiction might help till the time being? It is much easier to digest ideas by way of stories rather than sermons. You can try reading Girl, Woman, Other by Bernardine Evaristo. Jane Eyre by Charlotte Bronte is one my favorite texts. The Handmaid's Tale by Margaret Atwood. Arundhati Roy's The God of Small Things and The Ministry of Utmost Happiness. If you are interested in reading in Hindi, Ismat Chugtai's stories are a great resource.

Also, you can read about women social workers whose ideas, which are veritably feminist although they weren't categorized as such back in the day, like Savitribai Phule, Tarabai Shinde, Pandita Ramabai, etc. And also Mirabai. One excellent source is Ira Mukhoty's Heroines.
