fustican 

One who holds a large number of unfounded or poorly thought out opinions, especially on political or religious topics. Basically a gullible know-it-all.

My brother is a fustican; he never has good reasons for what he says.

The haze of confusion experinced by 'old folks'. Like confused only more acute and just for oldies.
