make choices who would be more open to change, and civil rights.
but of course that wasn't an issue with this election was it?
However, trump made racism, sexism, and xenophobia an issue, and he
made no bones about his racist, sexist, and xenophobic views, so yes, those who were aware of those views who voted for trump did NOT have a problem with those views.
As for your point regarding President Obama, it wasn't as clear as you would like to portray. His position on that subject changed back and forth through the years, between civil unions and full marriage rights, but one thing he was always consistent on, civil rights for gay couples, that included hospital visitation, transfer of property and Social Security benefits.
"In 1996, as he ran for Illinois state Senate, Chicagos Outlines gay newspaper asked candidates to fill out a questionnaire. Tracy Baim, the co-founder and publisher of Outlines, dug up a copy of the questionnaire in 2009, cataloging the president-elects shift.
He had written on the 1996 questionnaire, "I favor legalizing same-sex marriages, and would fight efforts to prohibit such marriages."

Racism, sexism, and xenophobia was an issue this election, because one of the candidates ran on that, so those who voted for that candidate obviously had no problem with it. There was no middle ground, and his team appointments reinforce that view.
but it isn't only that, he made it clear who he would appoint to the Supreme Court, and that itself confirmed his views on civil rights, deregulation, and women's rights.
People who voted for trump knew exactly where he stood, and they had no problem with it
