Sexism

Sexism is commonly considered to be a discrimination and/or a hatred against people based on their sex rather than their individual merits, but can also refer to any and all systemic differentiations based on the sex of the individuals.

People usually talk about sexism against woman. Now more often we can hear talking about sexism against man. But what can we say about such unacceptable and sometimes even painful questions related to sexism against intersexes or transsexes?

Sexism against intersexes

Sexism against intersexes has only been recently identified, and the general public remains mostly unaware of it. Historically, most cultures (with few exceptions) hold that males and females are separate and distinct entities with separate gender roles and responsibilities. Infants who are born with ambiguous genitalia are either killed or receive surgical alteration of their genitalia to disambiguate their sex. However, nowadays there are people who express sexual attraction to the same gender.
Despite the fact that all the word try to be tolerant, there are a lot of people who do not tolerate homosexuals. Lesbians or gays are discriminated just because of their sexual orientation which seems abnormal for the majority part of society.
People who declare that they are homosexuals may have problems in finding job, having childs or becoming a victim of violence. These people are discriminating in various situations of the life: family, friends’ sometimes even government.

Sexism against transsexes

Sexism against transexes has been recently identified. Traditionally, transsexes are viewed as having psychological problem of gender identity disorder or more recently viewed as simply being radically homosexsual.
Transsexuality refers to the condition of being self-identified with the opposite sex.
The most typical forms of sexism against transsexuals are how many "women-only" and "men-only" events and organizations have been criticized for rejecting transfemales, and transmales respectively. Transsexed people often are a target of hate crimes as the traditional notion of masculinity and femininity is often perceived to be threatened by those who adopt a different sex later in life.

Finally, even if our society becomes much more tolerant does it mean that these people will not feel invisible sexism or discrimination?
