Does the Character of the Artist Taint the Art?

Turns out that Krafft is a Holocaust denier and a White Nationalist. Progressive art lovers everywhere spent vast amounts of wealth buying his "ironic" pieces only to find out that he wasn't really being ironic at all.

If you bought his kitchy "Hitler Idaho" teapot and thought it was an ironic joke and, in your subjective opinion, displayed the teapot as a provocative piece of dark humorous art, does the realization that the artist is a raging lunatic with hatefully poisonous beliefs change the teapot?
