I don't think it hurts, nor costs too much to use a scent free/deodorizer soap on your clothes and yourself, but I agree with the assessment that it mostly depends on where you're hunting. My Dad and uncle see plenty of deer when they are working the farm smelling like sweat, diesel, their lunch, regular scented body soaps, deodorant, clothes detergents, etc. etc., so there's really no reason for us to think those deer aren't acclimated to those daily human scents.
