This is true. An employer can find other ways of letting an employee go.
Now we have had a few threads lately where CDers don't want to be labelled transgender or be in any way associated with the LGBT. I have tried to point out to you without shoving your faces in it that you may need them some day and their representation is actually a good thing.
What happens if you are outed at work and it causes a disruption? You could lose your job. What happens if your landlord gets complaints from other tenants they have a guy in the building that likes to wear dresses. He could kick your rear out.
The LGBT are helping you in those important areas. Just something to think about.
