I'm not trying to be pedantic or difficult here, but the beard and robes are part of cultural heritage, not an intrinsic part of Islam. Others from the same part of the world may dress similarly and get similar negative responses yet adhere to a different or no faith at all.
Yes, halal food might not be always readily provided, but neither is vegetarian or vegan or gluten-free.
I do agree that there has been more specifically anti-Muslim feeling in recent decades, coinciding with British involvement in Iraq in particular and the rise of Isis. But Asian friends of mine from Hindu and Catholic backgrounds have also experienced racism (surprise, surprise) - all down to their skin colour.
