I chose "other" because I've never felt personally alienated by the homosexual community, but I've seen this happen to both strangers and loved ones, and it's mostly a mixture of luck and lack of active involvement in the community that I haven't experienced it myself.
I do remember an awful time in early high school when that horribly-researched study was released that supposedly proved that bisexuals didn't exist so I convinced myself I was straight and in denial. That taught me a great lesson in that although the scientific method is awesome, you can't trust every article with the word "science" tacked on - you have to actually research it yourself. Learning years later after uncomfortably picking up the bi label again that the study was debunked was such a beautiful piece of news.
