Is TyRa BaNkS BiAsEd AgaInSt BuTcH lEsBiAnS?

Since becoming a loyal fan of "The Tyra Banks" TV show, I noticed that when she does her gay segments she never has butch lesbians as guest, but only feminine lesbians. Does Tyra prefer to favor feminine lesbians and feminine gay men because that's who she's use to being around?

People should be made aware that there aren't just feminine gays and
