We probably are getting a point of view on here that is biased on the accepting side. I mean all the people on this site--gay, straight, male, female, etc--are obviously a little more open-minded than the average person to be on a site like this.
Anyway, I think it would partially depend on the area that you live in. Some areas are definitely more accepting than others. I've also run into a lot of straight people who are very friendly to gay people but definitely still think in stereotypes they don't realize they have built into them. For instance a coworker of mine who asked another coworker who was somewhat flamboyant and gay "no offense or anything but are you gay or just very eccentric?" To me this implied that she felt gay people seem eccentric or eccentric people seem gay. I know she didn't mean anything by it but I think that it still shows how people hold onto stereotypes without realizing it.
My grandparents (who I do know think that being gay is a choice and think it is an attempt for people to be weird) had a gay couple move into the house next to theirs on martha's vineyard (for those who don't know, martha's vineyard is a very gay friendly island off of massachusetts). I remember them telling the rest of our family "the couple next door to us are fags, but they are a lot of fun. We had them over for drinks last week." (this was before they found out that i'm gay--they know now but they don't discuss it).
I think the reverse is true also though. I know I often find myself assuming that the well educated and "white collar professionals" would be more accepting of gay people and I find myself being more nervous around people who seem "rougher around the edges" or less educated. I've actually found in many instances that the people I assumed would be less accepting are actually the more accepting ones. |
