Harvard students shocked to learn that when they encourage graffiti, they might not like all the messages

This sounds different from the other cases in the report. It sounds a little like some pro Tibetian protesters decided to put up anti China messages. Its also possible some frat boy did it to be "funny" but the whole genocide thing seems aimed at mainland Chinas practices with groups it doesnt like.

When we decide to strip wallpaper and do-over a room in our house, it has become a tradition to graffitti the walls before we do so.

I'm constantly amazed what comes out of my own crayons and markers, let alone what the kids put up there. It seems like writing on the walls is deeply ingrained as "naughty" so the resulting writings and drawings tend toward being naughty. Lick Bush in '04. Crude childish cartoons of people with giant fart bubbles floating them away. Various child- and adult-generated exhortations to destruction or subversion. Flag sticker with flames drawn around it. Etc.

Some of our friends have adopted this same practice, and this also results in much graphic "naughtiness" by both adults and children.

Even when it is okay to write on the walls, there is something forbidden and antisocial and contrarian about it. I don't know why this is, but it seems to happen every time.

When I was around MIT every day, I noticed anti-Asian graffiti very frequently:

I haven't been on campus enough lately to say what it's like now.
