Legally yes, but call it retroactive cancelation then... Something that is legal today but might be shameful or even ilegal in 30 years.

An example: a young person paints his face in black before going to a party. Decades later, black face is a thing and people find out about that party and it's now a shit show for the guy that is a prime minister of a country. There's no legal prosecution, but cancelation is even harder to deal with.
