The feeling of injustice is based on a persons evaluation that in a certain situation a principle of justice has been broken, which results in that person or someone else being denied something they deserve. Reactions to injustice, among other things, depend on the characteristics of the event, but also on some personal characteristics like injustice sensitivity (Ćubela Adorić i Jurkin, 2008). Sexual orientation is an identity component which includes both sexual attraction and emotional attraction towards another person, as well as the behaviour which might result from it (APA, 2015). Individual's attitude towards different groups or people can be considered one of the main predictors of that individual's behaviour towards them. The goal of this research was to examine the sex and diet differences in injustice sensitivity and attitudes toward homosexual persons. To examine the injustice sensitivity the Justice Sensitivity Scale was used (Ćubela Adorić i Jurkin, 2008), while to examine attitudes towards homosexual persons the Attitudes Towards Lesbians and Gay Man scale was used (Herek, 1988). There were 47 male and 110 female college students participating in the study (N=157). A statistically significant difference was found in injustice senstivity when it comes to sex differences – women are more sensitive than men, but there was no significant difference when it comes to the dietary habits. A statistically significant difference was found in attitudes towards homosexual persons when it comes to both sex differences and diet differences. Vegetarians have a more positive attitude towards homosexual persons compared to omnivores, while women have a more positive attitude towards homosexual persons compared to men.
