This study investigates the impact of Islamophobic hate crimes on the British Muslim community in the aftermath of the 2017 terrorist attacks in the UK (United Kingdom), which were largely linked to Islamic extremism. Using qualitative research methods, the project explores the psychological and social consequences experienced by Muslim communities, focusing on hate crimes and discrimination. Through participant questionnaires, the study identifies key themes such as heightened anxiety, fear of public safety, and altered online behaviours. Respondents reported feelings of paranoia, identity questioning, and social withdrawal, reflecting the emotional and mental toll of Islamophobia. Additionally, the rise in Islamophobic abuse, both in person and online, demonstrates the widespread prejudice faced by Muslims post-terrorist incidents. The research highlights gaps in current counter-terrorism strategies, particularly in addressing the secondary harm inflicted on Muslim communities. Victims often felt neglected by law enforcement, leading to calls for more robust protective measures, such as increased police presence in vulnerable areas and better communication between authorities and Muslim communities. Participants also recommended educational reforms to raise public awareness of Islamophobia and more responsible media coverage to prevent further stigmatization of Muslims. The study emphasizes the importance of policy changes to reduce hate crimes and foster social cohesion.
