Trump supporters are pretty accepting of gay marriage, and millions of Trump voters in 2016 were Obama voters in 2008 and 2012. Planned parenthood had been around (and little changed) for decades before any swelling of far-right ranks occurred. The right had always been somewhat illiberal, but they had been kept in check by principled liberals and progressives. When right-wing racists was the norm in the 60s (and earlier), liberal colorblind antiracism overcame. When the right tried to censor ideas in the 70s and 80s, liberal free-speech ideals changed the landscape. Liberalism effectively moderated right-wing racism for decades, and nothing significantly changed in right-wing illiberalism which could explain left-wing illiberalism.
