Do I support terrorism if I wear a shemagh?

Wearing a shemagh for practical use such as keeping warm when it's cold and windy, does not make you a supporter of terrorism and terrorists. I can't say there won't be some people who see you wearing a shemagh won't think you might be a support of terrorism or a terrorist. Many schools where I do substitute teaching have female teachers who wear head coverings. I find this offensive; but, apparently the school district doesn't--they hired them.
