Lots of protestant churches have “communion”, and some of the bread in some of them is a cracker-like thing shaped kind of like a chicklet. I have been to protestant services where they do that now and then. They serve little paper cups like medication cups with a little bit of grape juice in them as well. Not wine. Welch’s grape juice or something.
And, of course, if one believes in “once saved, always saved” (and I don’t know if Trump does) then there’s nothing new to ever forgive. Some mainline protestants hold that in a way, believing that faith alone is sufficient for salvation. Some believe Jesus’ sacrifice is like a robe that “covers all our sins” from the sight of God.
I don’t believe any of that, but a lot of people in this country do.
So basically, the above complaint is that Trump is a protestant.
