As to the Gender of Angels, ...
... aren't the angels in the Bible, the Qu'ran and the writings and visions of mystics described as being of the male gender? In languages where nouns have gender, angels are usually male: EL angel, O anjo, IL angelo, LE ange, DER Engel.
Also, judging from the reaction of people such as the parents of Samson in the Book of Judges, angels are not cute and sweet, but rather majestic and overpowering to the point of being actually intimidating.
God is subtle, but He is not malicious. (Albert Einstein)
