From a scientific standpoint, there is nothing “disturbing” about the two signs.

I imagine the student was fairly young - and not concerned with philosphy. (Oranges are a fruit (fact.) I don’t like oranges - they are too messy. opinion).
OTOH, I imagine that many moral truths can be tested or proven. Just take a look at an inner city community with their high number of single mothers, kids that don’t even know their fathers, and then the crime that leads to, which then leads to gang murders, etc.
Of course, if one thinks that type of life is morally acceptable (drugging, pimping, stealing, and murdering) - then I guess those areas would be a prime destination spot. And; I guess they are for many.
