It is not uncommon for the meaning of a word understood for hundreds of years to be easily overturned and narrowly re-defined as offensive. A word which was once neutral can develop an overwhelmingly negative connotation and be viewed as bad in itself. As a reader primarily of non-fiction by authors spanning hundreds of years, these shifts are not difficult to find.
"I have said that we must also learn to discriminate, and at this particular time that point needs insisting on. Many run after novelties, charmed with every invention: learn to judge between truth and its counterfeits, and you will not be led astray. Others adhere like limpets to old teachings, and yet these may only be ancient errors: prove all things, and hold fast that which is good. The use of the sieve, and the winnowing fan, is much to be commended. Dear brethren, a man who has asked of the Lord to give him clear eyes by which he shall see the truth and discern it bearings, and who, by reason of the constant exercise of his faculties, has obtained an accurate judgement, is one fit to be a leader of the Lord's host; but all are not such. It is painful to observe how many embrace anything if it be but earnestly brought before them. They swallow the medicine of every spiritual quack who has enough of brazen assurance to appear to be sincere. Be ye not such children in understanding, but test carefully before you accept. Ask the Holy Spirit to give you the faculty of discerning, so shall you conduct your flocks far from poisonous meadows, and lead them into safe passage.
When in due time you have gained the power of requiring knowledge, and the faculty of discrimination, seek next for ability to retain and hold firmly what you have learned. In these times certain men glory in being weathercocks; they hold fast nothing, they have, in fact, nothing worth the holding. They believed yesterday, but not that which they believe to-day, nor that which they will believe to-morrow, and he would be a greater prophet than Isaiah who should be able to tell what they will believe when next the moon doth fill her horns, for they are constantly altering, and seem to be born under that said moon, and to partake of her changing moods. These men may be as honest as they claim to be, but of what use are they? Like good trees oftentimes transplanted, they may be of a noble nature, but they bring forth nothing; their strength goes out in rooting and re-rooting, they have no sap to spare for fruit. Be sure you have the truth, and then be sure you hold it. Be ready for =fresh truth, if it be truth, but be very chary how you subscribe to the belief that a better light has been found than that of the sun. Those who hawk new truth about the street, as the boys do a second edition of the evening paper, are usually no better than they should be. The fair maid of truth does not paint her cheeks and tire her head like Jezebel, following every new philosophic fashion; she is content with her own native beauty, and her aspect is in the main the same yesterday, to-day, and for ever." (Spurgeon, C. H. Lectures to My Students: Complete & Unabridged. Ministry Resources Library, Zondervan Publishing House, 1989. pages 207-208)
Once we are born again through faith in Jesus Christ we are divinely enabled to learn to discriminate as Spurgeon exhorts: to know the truth and hold fast to it. The presence of the Holy Spirit within us guides us into truth, convicts us of sin and reveals the wickedness in us which loves some people more than others. We can renounce our wickedness revealed by our sinful discrimination because God has discriminated between truth and error in His word and in our hearts. For the glory of God and our good we are wise to learn to thus discriminate, not because we are God but because we fear and seek to honour Him above all. Society can base beliefs and practices on the sinking sands of political correctness, fear of reprisal or censure by man: as followers of Jesus Christ we ought to love one another as He loves us, give more grace and walk in compassion towards all. It does us no benefit to point out tendencies of others to unfairly discriminate until we first learn to discriminate truth from error and walk with Jesus (who is the Truth) faithfully ourselves.
