This is basically defending the creepy idol culture as something "pure and innocent". The connotations of those sneaky photographs (a clear violation of personal rights imo) along with flushed appearance/heavy breathing is definitely not one of "oh, this is all innocent".
I mean, I agree that it could be worse. Realistically, since Tama doesn't care, it's really no issue at all. But I still feel it's a weak excuse and it didn't have to be there ...
