"People in same-sex relationships" is not the same as "same-sex-oriented people."
"People in opposite-sex relationships" is not the same as "opposite-sex-oriented people."
If someone wants to have nasty unnatural sex behind closed doors, I consider it none of my business and that ought to make me defined as "tolerant."
However, I can't stand for them holding their vulgar parades in public streets and recruiting confused school-aged children to their deviant lifestyle. I suppose that makes me "homophobic."
I can not, not do I wish to, parade down the street wearing what I would wear in the bedroom to promote the "missionary position," which happens to be my favorite brand of normal heterosexual intercourse.
