- Are people born homosexual, or is it a free choice?
Hmm, maybe it's both? Some people say they've felt attracted to the same sex their whole life, whereas you get people who decide many years later that they want to try dating someone of the same sex. If you could take a homosexual person and change their childhood upbringing multiple times and see whether that affected their sexuality later in life we'd find out if the environment played a role. However until someone invents time travel we'll just have to keep guessing :(
- Why are people homophobic, are they hiding their own sexuality?
Fear of the unknown.
- Is it socially acceptable to be homosexual?
Who cares if it's socially acceptable? Do what makes you happy :)
