They might do, "Faith" schools have already faced challenges for refusing to employ people not belonging to their religion.
As an aside, it's hard to see how you can believe in the brotherhood of man and also be a racist.
Its the interpretation of what makes an individual a rascist within your eyes that might the problem.
Restriction on immigration does that make a rascist in your eyes ?
The word Paki does that make a rascist in your eyes ?
Telling/ laughing at Irish jokes is that rascist ?
Not wishing a mosque to be built within your comminity is that rascist ?
Its endless ....... and some are angry some or confused.
And why should we trust yours, the governments or anyones elses judgement on what should be considered rascists behaviour.
You see I think we instinctively know what rascists are, but the boundaries may well be blurred just now and hijacked by the authorities to subdue freedom of speech and thought, thats the worry.
