Not at all!
I think it is a wonderful aspect of her personality (as we as fans see it). That is, she is accepting of people who have differentiating sexualities from the majority.
For me personally it is her dancers I find alienating.
I mean, if they're utilized as they were in Dome Tour 2001 I have no problem with them.
Post 2006 though, they are almost featured in every live, and as such I've begun to fantasize another tour in the vein of DT2001, or even Stadium. Even PoM, a toned down concert in comparison to the opulence and pure grandeur of AT2008/2010 and PCDL, still really overused the dancers.
Of course, I realize that this is really a clash of opinion. Ayu thinks that they add a little bit more. As a fan, I think they should be used when most effective, otherwise this overexposure just looks flowery.
Sometimes I just want to see Ayu and the band. Sometimes there doesn't need to be excess.
Sorry for being off-topic, just my two cents about Ayu and alienation. When she's alone on stage, she just seems to connect to the audience far more. Not that this doesn't occur in the modern Ayu era, it's just not as common. :/
