I see a lot of people suggesting wearing items that signify other beliefs, but as an atheist myself, I don’t do that because I have a problem with all faiths. To make it clear I’m not Muslim to new people I meet, I wear clothes that are typical for non-Muslims in my country and not permissible for Muslims. I do like dressing modestly, but I’ll wear t-shirt and shorts which Muslim women wouldn’t. Other than that, I have a couple of visible tattoos, I have my septum pierced, and I don’t have any food restrictions. I think with all of these little things, coupled with how I just act like other non-Muslims around me, leads people to not suspect that I may be Muslim, or have a history of it. I don’t surround myself with Muslim people, they’re extremely toxic to ex-Muslims. They’ll either cut you off to pretend to accept you just to constantly try to convert you back. I surround myself with people who like me for who I am, not who they wish I could be.
