Prior to addressing your comment I'd like to make it clear that any jokes or insults with the intention to harm are not acceptable.

To address your comment - these things are not often as clear cut as you'd make out. The real world just isn't like that. Where this particular situation gets murky is that one of the men in question has replied to the charge against him, giving his side of the story:

  I had decided forking someone's repo is a new form of flattery
  (the highest form being implementation) and we were excited
  about one of the presenters projects; a friend said "I would
  fork that guys repo" The sexual context was applied by Adria,
  and not us.

Whether you agree with his comments or not, he should have the opportunity to present his side of the story before being 'sentenced'. In this case that hasn't happened and so he's out of a job for what may have been an innocent comment taken in the wrong way by OP.

It's for these reasons that vigilantism is never a solution to these issues. It's possible that in this case a deeper divide will created between those who see the comment as trivial and those who do not. The outcome will be that the former group pays less attention to more serious issues because of what they see as "crying wolf" by some parties and the latter group becomes more emphatic on trivial issues which "never get resolved". This helps neither group and does nothing to reduce these problems in the future, a net negative for all involved.
