Iggy Azalea is comparable to Lady Gaga, in that, she only feels comfortable "firing back" at hasbeens or "small fry." Iggy Azalea is not going to fire back at female rappers because she doesn't have the balls or fortitude to do so. But she will fire back at Australian magazines over a cover shoot or get T.I. to fight her battles with hasbeen rappers like Snoop Dogg. Likewise, Lady Gaga doesn't have the balls of fortitude to fire back at Madonna, but she had no problem attacking a "small fry" celebrity like Kelly Osbourne (who ironically never even insulted her). These type of personalities are inherently weak-willed, lack self-esteem, and generally never question or challenge higher authority. Psych 101, kids.
