I haven't looked into McClure's offenses beyond what the article talks about, but those slides seem totally innocent to me (it's a joke targeted at VCs more than anything else), which just makes him seem less guilty in this context ('cause why not just use real evidence then?). No comment on his actual guilt.
This quote from the linked article (from Chris Sacca) seems apt:
Over the last week, I have spoken with friends, friends of friends, heard from people from my past including stories of how I’d behaved, and read incredibly thoughtful and courageous essays. I’ve learned that it’s often the less obvious, yet pervasive and questionable, everyday behaviors of men in our industry that collectively make it inhospitable for women.
There is definitely a pervasive issue here in software culture as it relates to women, and maybe singling out and punishing individuals is the only way to combat it—but my first inclination when making moral judgements is to consider intent. When I see those slides above, I see the work of someone whose 'filter' and sensitivity to not offending people is lower than average. I do not see immoral activity, however.
I will gladly look at more info. on McClure's offenses if anyone wants to share—and I'm perfectly aware he may not be an instance of what I'm about to mention here—but, we recognize there is a systemic issue with gender equality in software which needs to be fixed, but is there maybe a better strategy than punishing individuals who get caught displaying symptoms of the admitted, systemic issue? (or do we retract the claim that there's a systemic issue? —cause those things are at odds: is it the fault of the culture these people are a part of, or have they personally done something egregious? We could mistakenly go too far in either direction, but maybe our aim will be better if that part of the issue is at least considered...)
