I didn't say Goldwater created the Republican Party. I said Goldwater, and several of his contemporaries created the conservative movement. That movement today has been co-opted by people that actually share very little of Goldwater's or Buckley's philosophical beliefs.
Goldwater laid the foundation on which Reagan built a movement.
In any case, Goldwater didn't "create" either. He did revitalize the conservative movement in 1964 to take BACK control of the Republican Party, and deserves credit for that (the last time conservatives had controlled the party prior to Goldwater was the 1920s)
And there's no doubt the Goldwater of 1964 was not in favor of special rights for gays the way Goldwater c. late 1980s was. Lyndon Johnson was briefly caught in a scandal with a closest gay staffer hitting on men in the white house restroom, and Goldwater exploited it all he could and made reference to "Johnson and his curious crew". Goldwater c. 1964 wouldn't be caught dead endorsing "civil unions" or any other special government recognition of gay relationships/living together.
