In light of the scientific evidence that women tend to have a very strong in-group bias (https://www.ncbi.nlm.nih.gov/pubmed/15491274), I put together a list of YouTube videos featuring women speaking against feminism, and logically dismantling its central premises.

It seems to work better than any other strategy. It also works on feminist men - possibly even better, since they have a double-bias in favor of women.

Be sure to preface the list with something polite and respectful like "I'd be interested in hearing your thoughts on what these very intelligent women are saying in these videos".

It's also good to include a link to the NIH study (at the top of this post).

When you share this, don't add a lot of your own words - just let the women in the videos do the speaking for you. The goal is to do everything you can to keep them from having an emotional knee-jerk reaction and shutting down the conversation without considering the points.
