Shit on your own porch all you want.
Not sure how (or why) you've gone from "we shouldn't be judging other people's taste" to "I get to defecate wherever I want."
For some reason, you keep trying to shift the discussion to vandalizing someone else's property, which you don't own.
In that case, no, property ownership is generally not a subject of taste. Do you really think it is, asdff?
