Yes we do and usually every day and this without knowing the individuals. To say otherwise is not reality in the world we live.
How we dress what we wear, or don't wear for that matter, will always ‘reflect’ who we are to some degree. How we make that judgment initially often depends on if we will pursue engaging the individual..or not. We do the same thing with who we allow our children to "hang" with.....and should. Appearances aren't everything...but they do give a starting point.
When I said “we,” I meant Christians.
