I purposely have a big ole homeless looking beard specifically to keep people at arms length.
Ironically one time in a single weekend it backfired twice...on a Friday while doing planks/pushups on a yoga mat in a park I was attacked by someone yelling “get out of my country” because they thought I was a Muslim praying to Mecca. Then the very next day I went to fresh market and ordered bacon and baby back ribs from the butcher and was confronted in the store by a man who followed me into the parking lot to attack me for being a bad Jew and ordering bacon and ribs on the sabbath.
I’m neither Muslim nor Jewish, and even after learning this neither of my attackers were apologetic.
