Sick of Political Correctness?

I find myself disturbed when my efforts to exercise discipline over how I speak to others, and about others, is casually dismissed as “political correctness”. The brother of Jesus did after all urge us to tame our tongues. He wrote,

^“With the tongue we praise our Lord and Father, and with it we curse human beings, who have been made in God’s likeness. Out of the same mouth come praise and cursing. My brothers and sisters, this should not be. Can both fresh water and salt water flow from the same spring? My brothers and sisters, can a fig tree bear olives, or a grapevine bear figs? Neither can a salt spring produce fresh water.” (James 3:9-12)
