I've read the amendment.
When it's applied in an uneven fashion you'll get threads/arguments like this.
Examples:
1. Man decides to take a knee while the national anthem is playing while on the clock/job.
result: Media and employer decide he is off limits to be held accountable for his 1st amendment rights.
2. Man, not at work or during a work day, goes to vote wearing a shirt some find offensive.
Result: Court of public opinion has him tried and sentenced.
This argument is about the obvious double standard being applied as a result of media backing and perceived offence.
ps- I know it's really to keep your government from oppressing your speech.
