Attorneys are paid to be advocates for their clients. They can and should use any and every conceivable argument to do so and allow the court to decide the right and wrongs. They are exempt from personal moral judgment for any legal action within the court room. If it were any other way, accused rapist, murderers and child molesters would not get representation. Political platforms are also constructed to appeal to the electorate and are not always a direct representation of the personal morals of the candidate. You can argue the right or wrong of that, but trained lawyers don't seem to have a problem with it. (except my childhood buddy. He got his J.D and passed the Bar 6 years out of high school. He practiced for a couple of years but could not take the hypocrisy, so he quit and became a local paper sports writer and bartender)
Yet the Republican Party is full of loud mouthed loons in positions of leadership declaring that privatizing Social Security is the way to go. I know several Republicans who are against S.S. privatization, but they don't run the Texas version or the national Republican Party. They're normal people, so they don't have a great deal of influence, of course. It strikes me as strange that the "tea party" wing of the GOP is so absurdly influencial in the major party that took over the so-called "movement," and made it their own. As a result, the Republican leadership is made up of either actual extremists, or pols pretending to be extremists so they can win their primaries. And there are large numbers of the latter. When the "tea party" influence wanes (after some more election losses), you'll see these closet non-radical conservative Republicans suddenly come out of the woodwork. This outcome is so predictable that one has to wonder why the average "normal" Republican doesn't walk away from his/her party, and attempt to form/join the conservative wing of the Democratic Party, which could really use their numbers. After all, several of those Republicans I know are pro-choice, socially moderate, fiscally conservative old style GOPers, very similar to the white Democrats gerrymandered out of office in Texas and elsewhere, of which there were many until fairly recently.
