A war of words erupted on LinkedIn over the weekend when Telstra\u2019s head of security services Jacqui McNamara took issue with an article by Startup Foundation founder Daniel Mumby about the lack of women in startup land.\nMumby\u2019s article, \u2018Ladies, get off your \u2018buts\u2019 and build your business, no one will do it for you\u2019 drew fire from McNamara who said she was \u201chorrified today to find in my newsfeed an article mansplaining about how women need to get off their butts.\u201d\nThe article was \u201ccomplete with graphics of various shaped women\u2019s rear ends, no I\u2019m not kidding and I do mean today, in 2017,\u201d McNamara said in her post. [Mumby has since removed the image and replaced it with another one.]\nIn a startup sector struggling to create a culture of gender diversity, Mumby said that although women make stronger and better entrepreneurs than men, few will ever take the \u201cleap of faith\u201d and start a business.\nHe argues that there are too many \u2018buts\u2019 (yes, pun intended): 'But I have a family to look after\u2019, \u2018But I have a house to clean\u2019, \u2018But I don\u2019t have the skills\u2019. He suggests women watch the movie Joy, which is \u201cthe exemplar of how to overcome every single \u2018but\u2019 and more".\n\u201cSeriously, if you\u2019ve carried a child and given birth, the idea of imagining and building a business is easy by comparison,\u201d Mumby said in his article.\n\u201cAnd if you\u2019ve ever raised a child, growing a business is easy by comparison,\u201d he said.\nMcNamara claimed that \u201csuccessive complaints of disgust and shock were met by the author with encouragement to lighten up.\u201d\n\u201cFrighteningly, one or two women joined the posse to say they had developed thick skin and found it funny. You know, I used to be one of the boys too, and I learned to laugh at jokes and comments designed to marginalise my gender,"McNamara wrote.\n\u201cI put up with sexism and misogyny daily and I felt tough about it. But I wasn\u2019t tough, I was hiding, being inauthentic and sacrificing my core beliefs to get along and get ahead. Actually, it didn\u2019t really get me ahead either. The best thing I ever did is realised this self sabotaging behaviour created an environment where the privileged few get to bully the others. It does the bullies and the bullied no good at all.\u201d\nMcNamara said diversity and inclusion are important because they create a culture where everyone can be authentic and bring their best.\n\u201cIt\u2019s time to ask LinkedIn and other social media sites aimed at professionals to stay professional and limit bullying and misogyny. I\u2019ve really had enough. Who\u2019s with me?\u201d she said.\nThere were more than 140 comments at time of publication including a short discussion between Mumby and McNamara on the issue of gender diversity, bullying and inclusion in the workplace. The social media joust, which ended with McNamara confirming that she wasn't seeking to intimidate Mumby, "just calling out inappropriate behaviour where Isee it,"can be seen here.
