From a fact based analysis, it's not bullshit. Read your history, look at current situation as data to be sifted through and it's obvious that the reality is different from the popular image portrayed.
Labeling the whole thing as "dead" is pure hyperbole, and probably a lame excuse not to get involved and do the hard work that is necessary to change broken stuff.
If it were dead and nonexistent, then people would not have been able to liberalize marijuana use in Colorado and Washington, nor approved measures allowing gay people to marry the people they love in several states.
Wow, tell that to someone who can finally have all the legal rights that most married couples enjoy. Or all the folks on the other side who are convinced that their own marriages are forever ruined and the country on the road to hell because some people can get married.
EDIT: To clarify, I fully understand that it's a problem that needs to be addressed. I'm against any injustice against any group of people, based on arbitrary historical prejudices or otherwise. I'm just expressing my opinion on how the people who decide which issues to address and how to address them are motivated by political convenience vs actual priority.
