I think that if the illuminati signs are more obvious now it's because things are changing and being taken to a next level. The NWO has to be established (soon ?) and they are acting according to a plan. I think that these Illuminati don't feel the need the hide anymore and most of the time the symbols are used to be recognized in their circles not specificaly for the public. You have to keep in mind that with regard to the number of people on this planet very very few are aware of this illuminati "thing". Only people aware of the meaning of these symbols can make an interpretation. For those who don't know it's only "fashion".
Plus, I don't see the effectivness of using blatant illuminati symbols in music video-clips to expose them. It's not only using the symbols but also the gestures. Sex being the major ingredient and Gaga is doing a good job.
Therefore Gaga's artistry and imagery is not anti-illuminati but rather a kind of "publicity". She is spreading their message. She is obviously not just saying I know you. She is also saying I love you, I need you, I want you.
The question here is not to say if Gaga is a good person or a bad person. She's being manipulated. What I'm not so sure is if she is aware of being a puppet and to have accepted to be one or if she doesn't realize.
Yes we have to spread love and be kind with our neighbour but there are evil people in this world so we have to be perceptive and not be deceived so easily just because her name has been linked to Michael's one.
