Dickhead who is gender fluid doesn't fall under a protected characteristic do they? Being non-binary isn't actually covered by law yet is it?
Female muslim employee falls under two.
Also efforts to force Muslim women to treat gender fluid (or trans) customers will only result in them no longer working in the industry, which isn't exactly increasing inclusivity.
What always gets me in these cases is the 'victim' always seems to have a portfolio of images of themselves ready to hand to the press. The alleged 'abuser' being from a religious or ethnic minority also seems to be part of the pattern.
Odd isn't it?
