Trump represents a threat to social liberalism. That's always been the issue, since before he took office. Trump is pushing back the liberal agenda that stands for same-sex marriage, socialized healthcare, federal funding for abortions, liberal judges on the SC, open borders and social welfare programs for immigrants whose livelihood will then depend on voting for Democrats, etc., etc. And I've yet to meet even one self-proclaimed modern feminist who likes Trump.
There's something of a culture war going on between a social-progressive and a more traditional-conservative view of the country. Both sides seem to believe they have morality on their side.
Liberals have always hated Trump and will continue to hate Trump. And it's not just Trump. It's the attorney general, it's Brett Kavanaugh, it's Kellyanne Conway, it's Lindsay Graham, etc. They'll generate faux outrage and spew vitriol at anyone who interferes with the liberal agenda. It's the same thing that's been going on for 2 1/2 years.
