What a retconning farce this is. 40 years ago you could not publicly endorse recreational drug use, atheism, or interracial marriages without a substancial block of society chastating you as an incorrectable heathen.

Fortunately for all of us, it's not the general population of millenials or boomers who decide what speech the government gets to prevent; it's experienced justices, who tend to take the constitution much more seriously than the average person.
