I was a Republican because I believed in a limited role for the federal government, state's rights, fiscal responsibility, free market economics, and the need for a strong defense (this was when the USSR was still around). But I also believed (and still do) in the absolute separation of church and state, respect for science, abortion rights, environmental protection, that tax cuts must be accompanied by commensurate spending cuts, and that liberals were equally patriotic countrymen and colleagues who deserved our respect and with whom we could amicably disagree. The Democrats were the other major American political party, they were NEVER the enemy. Back then, these views were not seen as incompatible with mainstream Republicanism. Sadly, there is no place in today's Republican Party for people like me. I and many others left the party. Or more accurately, the Republican Party left us!
Now, the wing-nut fringe of the Republican Party is its base. To be a Republican now, you have to disrespect science, be religious, oppose abortion rights, believe in a militaristic foreign policy, support tax cuts with no regard to their impact on the Government's fiscal solvency, disrespect the separation of church and state, not care about the environment, and think that anyone who disagrees with you is a communist! I'm appalled at the absence of intellect in the Republican party of today. It's downright scary that Republican members of Congress and state governors feel that they have to cow-tow to a loud-mouthed and intellectually bereft buffoon like Rush Limbaugh and that the party's recent presidential nominee selected the risibly unqualified Sarah Palin as his vice presidential choice in order to appeal to its unsophisticated base voters.
It really infuriates me that these superstitious nincompoops think that they are the guardians of national morality. Bill Clinton lied about his reckless and inappropriate, but otherwise harmless personal behavior and got impeached for it. George W. Bush lied in order to sell an unnecessary and unjustified war in Iraq that costs thousands of American lives and many more Iraqi lives and got reelected! Do they have their moralistic priorities just slightly out of order?
Because I believe in science, the rule of law, support diplomacy over militarism, am non-religious, support gay rights and same-sex marriage, care deeply about the environment and want to protect it, believe in balanced budgets, and believe that America is and should be part of the world, today's conservatives consider people like me to be communists (or Nazis, they can't seem to make up their minds) and view me as someone who "hates America." These people are so fanatical and their beliefs are so lacking in intellectual content that we have utterly nothing in common. It's so bizarre that believing in the Bill of Rights and in the due process of law makes you a communist of a Nazi. I wonder what sane Republicans like Abraham Lincoln, Dwight D. Eisenhower and Nelson Rockefeller would say if they could see what their party has degenerated into.
I left the Republican Party years ago and am now a registered Democrat. I now consider myself a political liberal, even though my views have not changed much over the years. I still harbor some hopes that the moderate wing of the party will resurrect itself, but I'm not holding my breath.
