So you're suggesting that in many parts of America, homosexuals need not fear undue discrimination in housing or hiring provided they "act normal"?
The fact is that they will still face such undue discrimination and if so, it's probably not in their best interest - at this time in history - to follow your advice in previous post.
I wish it weren't so, but until such impediments are removed from the housing and employment environments, many gay Americans are smarter to just keep quiet.

As to your comments about how to deal with a job interview, most of the questions you mention are none of the employer's business in the first place. The challenges come into play when the potential employer is made aware the applicant is gay and then refuses to interview and/or honestly consider their application.
And I'm unaware that gay Americans are protected in most workplaces from dismissal due to their sexual preference, though if you have a citation that shows otherwise, I'm happy to be educated.
Regardless, in those workplaces where gays are not welcome, the employer need only find a different reason for dismissal and it is that kind of undue employment practice that makes it wise for many gay Americans to just keep quiet and not publicly declare their personal preferences.

Be clear that I agree with your earlier premise in general. I look forward to the coming days ahead when gay Americans will no longer need to fear other people being aware of their homosexuality any more than you or I fear people being aware that we are heterosexual.
