PCUSA and other mainline Protestant churches (ex. United Methodists, Evangelical Lutherans, Episcopalians, United Church of Christ etc.) are fairly resistlib coded and have protested or rebuked Trump and his policies many many times through his presidencies. It comes at a cost because they’ve been hemorrhaging conservative leaning people offended by their positions on immigration abortion social justice etc. to conservative alternatives (ex. PCA rather than PCUSA) or to new and growing churches in the “Evangelical” movement, and don’t get replaced because people more on the left are more likely leave the faith entirely than to go to a left-leaning church. But they still do protests and whatnot anyway, you just don’t hear much of them because their share of the population is much lower and less loud than the very vocal Evangelical section.

There's a lot of denominations under the "Presbyterian" name. Some of them are typical conservatives, but others are progressive, marrying gay couples and ordaining women and openly gay pastors.
