He's entitled not to wear it, and to not support it. That being said, people are entitled to think his beliefs are garbage and are expressing as much.
He's pointed to his Orthodox faith and he's been dragged for it, some have even been pointing out his hypocrisy on that front as said church doesn't allow cohabitation before marriage and he lives with his girlfriend.
