Just because he says it doesn't mean it's so

 We’re back to the merry-go-round of a Trump presidency as of today, and along with much else, there has been a flurry of “how to manage” messages. 

Here is my quick one: 

Just because he says something is so, doesn’t mean it is. For example, he may claim he is “ending birthright citizenship,” but that isn’t under his power—it is enshrined in the 14th amendment—and he cannot simply reverse that. He has said that he is ending funding for those who protect gender identity, but that is tied up in (at least) federal rule making and probably actual legislation. 

The danger of assuming what he says is so is obeying what he says. On the above, for example, the door opens (further) for harassment of immigrants and trans people.

It thus is that much more important that we take his word for nothing. 

Do not obey in advance. 

updating to note: Others have observed that we don't have the text of any executive orders as of 5 PM this inauguration day, so we don't even know what he thinks he's doing with them.
