Gay//bi/las are they all go to hell ?

im and from thailand and im a christian singer(vocalist).and im gay. now a days people keep on telling me that gay goes to hell and i will go to hell since im gay.my question is why can't they see people as a people, human as a human ? does they(christen) never make sin infront of God ? and why all (most of christian) of them think they will go stright to heaven without following or practice the teaching of Jesus? why only gay ?
