Unflattering Language of A Christian

Proverbs 29:9(NKJV) 9 If a wise man contends with a foolish man, Whether the fool rages or laughs, there is no peace. Proverbs 29:9(AMP) 9 If a wise man has an argument with a foolish man, the fool only rages or laughs, and there is no rest. I just read a FB post where Prov. 29:9 was used to describe and justify their claim that Vice President Joe Biden is a fool. I'm assuming this comment was based on last night's VP debate. Now I'm not advocating for anyone in this post; good, bad or indifferent. However it does not give Christians the authority to appear unflattering before God and before God's people (whether saved or unsaved). It is God and only God that judges and condemns. Power is given to us to apply wisdom and knowledge of God's word to not be conformed by the things of this world. i.e. political persuasions. But back to the FB comment. It reminded me of a conversation I had with an unsaved person who defended their desire to remain non-Christian based on their frequent interactions with Christians who too often appear quick to leverage condemnation and vicious remarks according to their opinions. The person also spouted how these "Christians" will use the Bible to justify their opinions. And all this is done in the mighty name of Jesus; yes the disciples of Christ, those who are living to justify the teachings of Christ. Sadly, I've encountered this type of Christian all too often myself. I supplied you with two versions of the same scripture for a more indepth understanding. Previous posts by this author strongly indicate a Christian membership especially when they reference their health challenges which appear to be daunting. Therefore the weight of this comment struck me deep. No matter our political preferences, we are admonished by the word of God that we must at all times be uplifting in our conduct, even if it means being silent? The Bible was recorded for the expressed purpose to supply us with words to live by and to offer life through the Word of God as we display Christ-like character to a dying world. How can we expect to draw ALL men/women/children to the kingdom of God by calling others (whether they're Christians or not) unflattering names. IJS...non-believers need not respond.
