What earlier points of law does justice brennan use to support the courts opinion in the texas vs johnson case?

-The first amendment, Barnette case, and Justice Holmes

Explanation:

During the 1984 Republican National Convention held in Dallas, Texas, Gregory Lee Johnson burned an American flag protesting the policies of President Ronald Reagan. He was arrested with violation of a Texas statute and the Texas court tried to convict Johnson and was sentenced to one year in prison, and fined $2,000 but he appealed arguing that his actions were symbolic speech protected by the First Amendment. Justice William Brennan agreed with Johnson and agreed to hear the case where Johnson was represented by attorneys David D. Cole and William Kunstler.

in this passage from chapter 6 of "animal farm", by george orwell, what the author is ridiculing in this passage is the frivolity of some rules.

clover, the mare, believes she remembers that the fourth commandment forbade sleeping in beds because it was something that humans did. snowball, napoleon, and the pigs are brain-workers who look after the welfare of the farm. they are the obvious leaders because they are smart, and so they are entitled to eat the best food and sleep in beds. it is squealer, who says these lines making the difference between sleeping with sheets, what humans do, and sleeping in beds, what pigs do. the unwillingness to question authority makes the oppressed to obey without thinking.
