FCs 

FCs or fake Christians like the concept of being Christian in theory, but rarely apply Jesus's teachings to daily life. FCs tend to be self-righteous and hypocritical.

What are those FCs Jonathan and Reuben doing at my door with a pamphlet about Jesus Christ? I saw the same FCs staring at young boys and stalking/harassing a guy they had issues with the last few months.
