101 conversations I generally don't want to have...

This list now exists over at http://juliepagano.com/blog/2013/11/02/101-off-limits/ and will be updated there.

I keep saying that impromptu, unwanted feminism 101 discussions are exhausting and not a good use of my resources. Then people ask what I mean by 101, so I'm starting to make a list. This list will change over time - I recommend checking back.

I highly recommend checking this list before engaging with me about feminism if you're new to it. It'll save both of us a lot of time and frustration.

Diversity in tech

Women aren't equally represented in tech because biology

Nope. This argument is bad and the science does not support it. Unfortunately, every time you say this out loud, you are contributing to cultural problems that do decrease the number of women in tech.
