I feel like you're giving away your stance here with the "weird home lives" comment in relation to being openly gay. And I don't mean that I want even more personal stories to LinkedIn, but posting vacation pictures is hardly equatable with posting a hardship story about being gay in the workplace.

Being heterosexual is a privilege since it's the norm, so you don't have to worry about it. Being gay on the other hand can be dangerous, even life threatening depending on the country.
