Racial harassment is usually, altho

Racial harassment is usually, although not exclusively, directed at people from ethnic minorities. It may include jokes about, or gratuitous references to, a person's colour, race, religion or nationality. It can also include offensive remarks about dress, culture, or customs which have the effect of ridiculing or undermining an individual or fostering hatred and/or prejudice towards individuals or particular groups.
Harassment of people with disabilities can take the form of individuals being ignored, disparaged or ridiculed because of mistaken assumptions about their capabilities. Their disability rather than their ability can become the focus of attention and harassment can include inappropriate personal remarks, jokes or inappropriate reference to an individual's appearance.
Harassment on the grounds of a person's sexuality may be aimed at heterosexuals but is more usually experienced by lesbians or gay men, bisexuals or transgendered people. Examples of harassment relating to sexuality are homophobic remarks or jokes, offensive comments relating to a person's sexuality, threats to disclose a person's sexuality to others or offensive behaviour/abuse relating to HIV or AIDS status. The European Commission code of practice on sexual harassment points out that lesbians and gay men often encounter disproportionate levels of harassment relating to their sexuality. The response of lesbians and gay men to harassment may also be complicated by the fact that in order to complain about it, or confront it, they may have to be open about their sexuality with other people, perhaps for the first time.
Bullying is the exercise of power over another person through negative acts or behaviour that undermines him/her personally and/or academically. Bullying can involve threatening, insulting, abusive, disparaging or intimidating behaviour which places inappropriate pressure on the recipient or has the effect of isolating or excluding them. Bullying can take the form of shouting, sarcasm, derogatory remarks concerning academic performance or constant criticism and undermining. Bullying is to be distinguished from vigorous academic debate or the actions of a teacher or supervisor making reasonable (but perhaps unpopular) requests of his/her students.
