I didn’t like her book Atlas Shrugged.
Like everyone in this world she had the freedom to write her thoughts and views and put it out there, and thus the general public had their right to read it,agree or not and discuss it.
Maybe in her time (born in 1925 ) she had first impressions of growing up in Russia a very impressionable time that obviously stayed with her and thus her writing is affected by that.
We have grown up in freedom and therefore would not agree with that lifestyle if we were subjected to it after experiencing freedom here.
So looking through the lens of our lives one determines what is right for one self and find it hard to view it otherwise unless one places themselves in the mindset that she grew up in.
Also note that when her book was published in 1957 communism was a viable theory for many people so then she would write this to get other countries to follow suit as well.
Basically she jumped on a band wagon at the time and published her ideas on it.
To answer your question to whether its wrong to like Ann Rand , No its not wrong to like a thinker but you don’t have to agree on all of her ideas while on others its food for thought.
