Should aliens in fiction not be depicted as almost always naked?

Homo Sapiens is the only species on Earth, that feels embarassed and often times morally outraged, about being naked around members of their own species, a collective mental illness brought about purely due to social conditioning.
Since humans stand alone on the planet with this erroneous attitute, is it not reasonable to conclude, that in this regard they also stand mostly alone in the wider universe?
I think it logical to say, that most alien civilisations never develop this mass delusion about clothing, or clothing in general, safe for protective gear for special circumstances.
