Do LGBT have other civil rights? [View all]

I know some states, counties, and local governments have included sexual orientation as a group which can't be discriminated.

I know some companies included sexual orientation to the list of people they won't discriminate. Some have even extended benefits to the same sex partners of employees.

But, without these happening is there anything which protects LGBT from being discriminated against.

I know some say LGBT has the U.S. Constitution which all Americans have, but I am talking out being fired from a job, not being able to rent an apartment, and things not specifically stated in the Constitution. The things which made anti-discrimination laws and policies needed in the first place.

I know things are getting better for LGBT. I have been out in Alabama for about 10 years without discrimination (that I knew about) other than of course not being able to get married, a civil union or a domestic partnership.
