The american right pre Reagan was not really tied to the Republican party in the same way that it became, there was a movement post Nixon though to make the party more conservative. Republicans were a liberal party and democrats were a segregationist social democratic party. The john birch society right and the kkk right were different on their views around foreign intervention.

Also being a conservative who supports LGBT rights and supports legalizing drugs makes no sense unless their a single issue gun voter or something.
