You know, I wasn't there and she really doesn't give much context for the remark. But a) She has a kid and this is a reason she has put off starting her own company. b) In place of actually starting her own company, she is interviewing other founders with the reasoning that it will help her prepare to someday do it herself (which maybe it will, I don't know). c) She "shied away from" being an entrepreneur when she was young because of what she saw her father go through.

So, she had a secure, stable job, got married, had a baby and makes a blog about "some day wanting to have her own company". She has apparently never actually tried to found anything at all. It makes me wonder if she got mad because the remark hit a nerve. (My therapist used to say "If you throw a rock into a pack of dogs, the one that yelps is probably the one you hit.") Which in my book wouldn't be indicative of sexism at all.
