What would you do in this situation?

Dont call it off. How do you know that they will discrimminate or not if you dont go?? There is always a chance that they may hire you and with the economy in the condition its in, its quite hard to find a job and you would be lucky to find one. I was looking for a job for 3 months and I almost gave up but now, I have a job. I get paid pretty decently. My boss and coworkers all know that I am a . And did you know that it is illegal in ever state to discrimminate based on preferences, religion, age, etc? If they discrimminate you, you have every right to sue that business or call a certain number. I forgot. I'll give you a link for it. But I say go for it, dont back down and always take a chance because you will never know what your gonna get.
