"It" was the fact that Walker, years earlier, as an attorney, had represented the U.S. Olympic Committee (which is almost as vigilant as Disney about its brand) in a trademark lawsuit against the Gay Olympics.
That case went to the U.S. Supreme Court, which may be where Proposition 8 is ultimately headed, and you know what? Those "activist judges" sided with Walker, and the "Gay Olympics" lost.
And the other argument being put forward, that "majority rules" and because Proposition 8 won a majority of votes, those voters’ wishes are being violated by this ruling? Well, in the checks-and-balances system, the voters do not always have the last say.
In a precedent-setting legal exercise nearly 50 years ago, the California Legislature had passed the Rumford Fair Housing Act, which banned discrimination against ‘’colored’’ property renters or buyers. (Restrictive covenants about not selling to minorities were written into a number of deeds and real estate transactions.)
About 2/3 of California voters overturned the Rumford Act when they passed Proposition 14, which, like Proposition 8, had amended the California Constitution. Proposition 14 said Californians could indeed refuse to sell or rent to anyone for any reason. Eventually, the U.S. Supreme Court ruled that Proposition 14 violated the 14th Amendment, and it didn’t matter if 100% of Californians had voted for it -- it was racial discrimination, and unconstitutional. The equal protection clause that Walker cited in his Proposition 8 ruling is part of that same 14th Amendment.
