Trads are no different from other people. They may seem so because they are few in number and so things stick out.
Trads believe differently, and one would hope that belief at least affects some externals enough that people would recognize it.
Of course internals are the essential part, but if the barest externals are not manifested, the internals cannot be there. Such a person is secularized.
For example, someone who publicly admires Madonna and other disgusting things, or tells filthy, immoral jokes in order to taunt someone else on a
Catholic forum, is someone who lacks the barest externals of the Faith.
