I think that some of the issue may be your framing. Even if Trump is just enforcing his executive orders, it is possible that the orders themselves are anti-democratic.
If Trump's executive orders were simply changes in policy then they might still be bad but they wouldn't necessarily be a threat to democracy. The issue arises in that his executive orders go beyond that to attempt to attack worldviews that he doesn't like. "Gender non-conforming people cannot use a given bathroom" is a policy. "There are only two genders" is a worldview. Even though I disagree with both of them, the second is a much more anti-democratic.
