Using the name of Hazrat Khadeejah (radhiyallahu anha) to promote feminism

Q: In regards to the fitna of feminism arising, alot of our Muslim women have fallen for this wherein if you try to advice them that university offices is not a place for a Muslim woman, their argument is Hadhrat Khadeejah (radhiyallahu anha) was a businesswoman. My 2 questions are: 

1.I find that using Hadhrat Khadeejah (radhiyallahu anha) as an example of why they want to work in the corporate sector saying she was a businesswoman, etc. is very disrespectful towards the mother of the Muslim women. How do I explain to them that using the Sahaabiyyaat as examples is very disrespectful? 

2. How do I put forward to them in a way that they would understand that Islam and feminism does not go hand in hand?
