Yes, really. You are keeping the very thing you despise relevant simply by the constant chattering of her name and music, her every move (be it negative or not). You can tell yourself whatever you like, but that's how I see it. The fact of the matter is, that Gaga is the "it" artist and with that, comes immense scrutiny. Once your top dog, everyone initially wants a piece and then eventually wants to see you fall. The media hasn't exactly gotten to that point, but the people certainly have. I see chatter all over the net from envious fans who wish their fave artist was doing as well as Gaga. It's the same cycle over and over again. I realize that there are legit people who don't like her and never have, but hating on her is becoming a fad in itself. Again, just how I see things.
No, it really doesn't help her at all. Not any more than your constantly vocalizing your desire for Rihanna to go away helps her career. Were I a mainstream music "critic" or media personality paid to promote her album or a fan of hers (who doesn't illegally download her "music"), perhaps I could buy your argument--but I happen to be neither, so your argument makes no sense whatsoever. Internet forums are for discussion--many things are shared all across the board, spanning from irrelevant threads debating which restaurants are good and which aren't up to standards, to more relevant topics such as debating whose presidential legacy had the best/worst impact on a given time period. Arguing that voicing our distaste for Gaga somehow "helps" her is about as moronic as arguing people voicing their dislike of, say, George W. Bush's presidency somehow "helps" him.
Just like with Justin Bieber and other annoyances, it is the media, through its constant mention of her, who keeps her relevant. There's nothing one can do but wait it out--but I have the right to express my opinion while we wait for her to fade, and I intend to use it, just as you have repeatedly voiced your opinion on Rihanna. How are we any different, in that regard?
As for "envious" fans, I daresay you ought to re-learn the definition of the word "envy." People who envy do so because they lack something others have. All the artists I happen to be a fan of have more talent (vocal, lyrical, musical, and stylistic) than Gaga. Therefore, none of them have to "envy" that artificial attention whore, or any of the others who are popular within the mainstream. Do I wish they had as many "fans" as Gaga does? No. In my perspective, it's all about the quality, not the quantity. Gaga may have a lot of fans now, but I could say the same thing about Justin Bieber, and you know what they have in common? The bulk of those fanbases are composed of impressionable pre-teens and teenagers who wouldn't know music if it danced naked in front of them and slapped them in the face with a sequin glove. I give them five years to get over their "Gaga" and move on to the next trite tart who comes along. Just like Justin Bieber's fans, Gaga's present fans are superficial fans at best, because she's done nothing worthy of their lasting affection.
I would rather belong to a smaller fanbase composed of people who actually know what real music sounds like (and can recall music history, thus recognizing when someone is blatantly ripping off other artists.) I'm much happier being a fan of lesser-known artists who have no need for auto-tune, electronic beats, superficial lyrics about sex/alcohol, or desperate gimmicks, because they can carry themselves through talent alone and have the one thing neither Gaga nor most of her mainstream contemporaries possess: class.
Moral of the story: Popularity does not equate with quality--in fact, in the majority of scenarios, the more popular something is, the tackier it is, only because the majority of people have a phobia of material which actually makes them think, and a penchant for animalistic sex and violence (hence the success of mainstream music and professional sports.)
I, for one, do not adhere to such pedestrian tastes.
