have you excepted jesus christ as your saviour? ahve you asked him to come into your life,do yo0u desire to know him for yourself,your own personal relationship with him.if you have then you a re christian,its not wrong to have questions,ask god about them,how it sounds to me is that your church or the churches you ahve been brought up in have not been very acepting to other people,and you are right that is no way the message of christ,christ came acepting everyone,the door is open to everyone,just as the church door should be open to everyone. i come from an excelent church that celbrates the divercity of cultures and backgrounds,the door is open to everyone,because jesus arms did just that.i think al you really need to do if find a good church that has the same values as you do so you can nurture your faith.not with hypocrites but with god loving people who love people aswell!
