In most states it is illegal to hide your face via mask or makeup while in public. Just saying, not agreeing.
Well, there are a lot of things that are illegal in a lot of places. Unless you're a member of some 'protected class', which appears to include members of a certain religion, the name of which shall remain unnamed as the religion of peace...
Have I mentioned that I'm a guy? (and would wearing a burka mean that I'm trans-muslimed, or something?) Might be nice to be a member of TWO protected classes...
