Don't make personal attacks on HN. If you have an argument, feel free to voice it, even strenuously, but it's considered gauche here to address people who disagree with you directly and comment on them or their personal motives.
Impugning the motives of people you disagree with is a personal attack, and it's unacceptable behavior.
"Typically this term refers to a rhetorical strategy where the speaker attacks the character, MOTIVE, or some other attribute of the person making an argument rather than attacking the substance of the argument itself."

Arguing against preservation of an artifact—based on the the opponent's ostensible motive that "we should glorify some sick mind" who created the artifact—is a personal attack. It is unbecoming, and it is prohibited on HN.
