Perry vs. Schwarzenegger is going on right now in California. The case is two same-sex couples who were denied marriage licenses last year against Proposition 8 and its defenders (wikipedia). Schwarzenegger's name is on it technically- he and his legal counsel refused to support Prop. 8, and the defendant in the case is ProtectMarriage.org, which makes this case gloriously direct. The Good Guys vs. The Bad Guys.
Here is the Prop 8 Trial Tracker, hosted by some dedicated people at Courage Campaign to bring day-by-day coverage of the trial. I've been following along with wide eyes and bated breath- for this is, indeed, history in the making, and may result in gay marriage bans being ruled unconstitutional in the United States. There are a lot of prayers, emotions, and tears all over the country right now. Their site has all the in depth legal info about what makes this case historically interesting (besides the obvious) such as comparisons to the tactics of Brown vs. Board of Education. The issues at stake are not just marriage, but gay rights in general and federal recognition of the oppression of gays as a class of people. Three states have ruled gay folk a "suspect class"- people discriminated against as a group, including California.
Go there and read it, and possibly take a break to cry of joy. Read the comments to each post too, if you have the time; there are a lot of stories and memories there that people have shared.
