I won't pretend to understand what it's all about, but I do know one thing:
Prop 8 is not about anyone taking away anyone else's rights. The rights are already in place by law. I know this because I took the time to read the California Family Code.
297.5. (a) Registered domestic partners shall have the same rights,
protections, and benefits, and shall be subject to the same
responsibilities, obligations, and duties under law, whether they
derive from statutes, administrative regulations, court rules,
government policies, common law, or any other provisions or sources
of law, as are granted to and imposed upon spouses.
