With regards to the stalking and threats aspect of this article, I think that isn't something that can or should be dealt with by the community. Matters of that nature really should be presented to the authorities. Yes, it is horrible. Yes, it crosses the line. I just don't think there is much that the gaming community can do about someone who determinedly stalks someone even away and apart from the regular channels of communication like game forums.
The rest of the points being stated are not new and this isn't a new problem. The solution, IMO, does not start with angry articles of outrage. It is a societal problem that honestly begins with how responsible parents raise their children for the most part. By the time we start seeing the sexist/discriminatory behaviour in a game forum or social media, we're already at the 'too late' stage for the ones doing it.
