Just because i am a Muslim!?

why do some people give me the dirty looks, why do they make rude and very harsh comments to me, why do they not sit next to me. i was born in UK and never been to a Muslim country, my parents are from Bangladesh, i practise try my level best topractice Islam and spread invitation to people to come to a gathering to know about islam, the true islam, Why do people think that muslim want to force people into Islam, this is not right as a muslim, we can only invite and teach others about Islam, then its up to the individual to accept islam or not, forcing someone into islam is not right, the Koran has reference of this. i dont know any kind of person who wants to kill any person, they why am i suffering from some elses action, those people are pushing me toward suicide.
