linked to the belief that men's sexuality is specialized. This causes many members of the gay male community to assume that the very idea that men can be bisexual is homophobic to gay men. A number of bisexual men feel that such attitudes force them to keep their bisexuality in the closet and that it is even more oppressive than traditional heteronormativity. These men argue that the gay male community have something to learn about respect for the individual from the lesbian community, in which there is not a strong tradition to assume links between notions about the origins of sexual preferences and the acceptance thereof. These views are also supported by some gay men who do not like anal sex (sides, as opposed to both tops and bottoms) and report that they feel bullied by other gay men's assumption that their dislike for anal sex is "homophobic" and want more respect for the individuality in which a gay man who does not hate himself may simply not like anal sex and instead prefer other sex acts such as mutual fellatio and mutual male masturbation. Claims of bisexuals adapting to heteronormativity Some forms of prejudice against bisexuals are claims that bisexuality is an attempt in persecuted homosexuals to adapt to heteronormative societies by adopting a bisexual identity. Such claims are criticized by bisexuals and researchers studying the situation of bisexuals for falsely assuming that same-sex relationships would somehow escape persecution in heteronormative cultures by simply identifying as bisexual instead of homosexual. These researchers cite that all countries with laws against sex between people of the same sex give the same punishment regardless of what sexual orientation the people found guilty identify as, that any countries where same-sex marriage is illegal never allow marriages between people of the same sex no matter if they identify as bisexual instead of homosexual, and that laws against "gay" male blood donors invariably prohibit any man who had sex with other men from donating blood no matter if he identifies as homosexual or as bisexual. The conclusion made by these researchers is that since there is no societal benefit in identifying as bisexual instead of identifying as homosexual, the claim that bisexuals are homosexuals trying to adapt to a heteronormative society is simply false and biphobic and causes bisexuals to suffer a two-way discrimination from both LGBT society and heteronormative society that is worse than
