The current high-levels of anti-Muslim sentiment in the US have resulted in Muslims being targeted for attacks. The most visible symbols of Islam are of course the mosques and Muslim women who wear black coverings of the face and body or men who pray in groups in the distinctive prostrate position.
But a lot of the anti-Muslim zealots are not the most knowledgeable of people and anyone who wears clothing that is unfamiliar is seen as a target. Sikhs are again getting hit and are bracing themselves for more. They have been attacked on previous occasions by people who mistook the turbans that Sikhs wear as Muslim dress, such as the attack in 2012 on a Sikh temple in Wisconsin where six people died.
But even wearing different clothing may not be necessary to make you a target. One can expect to see attacks on random brown-skinned people as well. I tend not to think about such a possibility and am not frightened that I will be a victim. But I have spoken to a few Indians and Sri Lankans who wonder if they too might not become targets, irrespective of whether they are Muslim or not.
We are living at a time when inchoate anger is easily aroused and people want to simply lash out. Unfortunately, many of them have powerful weapons and can do serious damage. At such times, there will be a strong temptation to openly distance ourselves from Muslims by word or deed so as to signal that we should not be targeted. That would be wrong. Muslims in the US are already feeling beleaguered and isolated. To have the rest of us deliberately dissociate ourselves with them would be to compound the problem.
