They ask these questions for statistical purposes, and employers don't have that data until they hire I think.(Original post by ThomH97)
Plus, 50 years ago is bloody ages for most people on here XD
I'm not sure what more the law can do that would have anywhere near the impact, the rest is up to society and time. I guess it could prohibit forms asking people to disclose their sexuality (although they tend to ask for gender, ethnicity and marital status) so that any rejection due to those would be after the face to face meeting which is easier to keep track of.
It would look good for a company to have lots of LGBT, non white, disabled (insert some other minority) people because it would make them look progressive.
Attitudes will change with time, especially around the world too.
How are you celebrating?
