How is that in any way the same thing?
It's the same thing because Washington State law requires companies serving the public to provide identical services to all customers and potential customers that seek to do business with them. You can't discriminate based on what you think of the customer.
General comment, but particularly DJS needs to read this, since he apparently didn't pay attention to my post about my daughter. I am opposed to discrimination against lots of people, including, but not limited to people located anywhere on the gender spectrum, any religious belief or none, any race etc. I am not now a member of any religious group, nor have I been for at least six years.
I just think a few people here would be well served by thinking through the possible results of actions they want taken. It seems that some of you are in such a rush to fence in a group you have made it obvious you don't like; that you can't see who else might get scooped up in your net.
Maybe I should stop expecting you to think about any position but your own.
