As long as men can go top-free in public, constitutionally, women should have the same right, or men should also be forced to wear something to hide their chests.
Therefore, ALL or NO ONE is the only constitutional equation possible. “Subjective morality” is irrelevant to our Constitution. It was considered indecent for women to vote in 1920, yet the 19th amendment was adopted on the basis of gender equality.
Clothing, or lack thereof, is also a matter of gender equality.
Annual protests will be held until equal rights to be bare-chested are enforced.
