Sure as shit Trump has put into motion a decree that any protester against trump or trump policy will be labeled

22. No. He is making speeches (no legal effect)

He is signing Executive orders (which have legal effect to the extent they direct executive branch agencies or interpret existing law), and writing internal memos - wildly outrageous, but no legal effect other than creating a basis to fire executive branch employees who don't comply.

The flag burning was (1) a speech (followed by a bunch more speeches/texts/etc.) and (2) an executive order. No decree involved.

(1) The speech was nonsense - and bore no relationship to the executive order.
(2) The executive order directed the department of justice to enforce any law, on any matter, which was violated by burning a flag. For example - Federal marijuana laws are not currently being enforced. But if you use an American flag to light one - guess what - now they are going to go after you for consuming marijuana, because you did so by burning a flag to light it. If you burn an American flag in violation of a no-open-burning ordinance - guess what - now they are going to charge you with burning in a no-burn area.

Trump has no idea what he signed. He has been yammering (that speech thing) about imposing a one year prison sentence for flag burning, but the EO said zero about a new law, and zero about a prison sentence. In fact, it expressly excluded prosecution for burning the flag as speech so long as it did not violate other laws.
