Yep
While I don't fully understand/grasp the work Christ did on the cross (as I'm a new Christian and just learning these things), I do notice people wearing crucifixes and crosses a lot and wonder "do they really believe? Do they really follow after Christ?"
When I was in jail, it was a "cool" and "gangster" thing to wear crosses around your neck or to get Christian tattoos. Often, even when I'm free, I'll notice violent gangster-like people wearing crosses around their necks. I believe it's often for show, for them to say to the world that they are really just good inside, a diamond in the dirt so to speak, when in reality they're just violent, wicked people. Wolves in sheep's clothing.
Prayer hands tattoos were also very common, along with slogans like "only God can judge me" and such - I can't tell you how many tattoos like that I've seen - almost all if not all their owners being terrible people.
