RE: Warren Court
We knew about the Warren Court. Some with the money posted billboards.
RE: "I cannot accept the premise that some evil force changed America:"
I don't recall that anyone blames some evil force.
If we're going to divide by generation who elected Clinton and Obama? -- and did so in the era when free speech had been restored compared to "the way is was.".
In the picture you paint, only the leftist socialist had the money. Of course you did not have sufficient resources. But what about all those endowments for Universities? Every building -- in fact, individual floors and rooms --- are named after donors. Could they have done something? An even simpler example. The last person who did not subscribe to view of the Constitution as a living document has retired from Harvard Law School around 2000. Today, a student never even hears that Constitution should be interpreted according to the Founding Fathers' intent; this cornerstone of our democracy is not even expressed as an opinion. Yet donations continue unabated. No matter what other scandalous cases we hear, rich donors support their schools without any regard to the subversion they promulgate.
I was not, of course, speaking about you or your group of friends. But the question needs to be answered. Plenty of serious money went to the Republican Party over the eight years of Bush administration. Not one that I heard of demanded to stop the growth of the government (by 56% under Bush), closure of the borders, etc.
You did what you could; it is not a question of this or that individual. But you cannot deny that there exist those with money and other means of power. They have failed to act when it was possible to do so.
