Why exactly is profanity sinful?

Exodus 20:7
"“You shall not take the name of the Lord your God in vain, for the Lord will not hold him guiltless who takes His name in vain."

Jesus said, "The good man brings good things out of the good stored up in his heart, and the evil man brings evil things out of the evil stored up in his heart. For out of the overflow of his heart his mouth speaks” (Luke 6:45).

And He said, "Either make the tree good and its fruit good, or else make the tree bad and its fruit bad; for a tree is known by its fruit. Brood of vipers! How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks. A good man out of the good treasure of his heart brings forth good things, and an evil man out of the evil treasure brings forth evil things. But I say to you that for every idle word men may speak, they will give account of it in the day of judgment. For by your words you will be justified, and by your words you will be condemned” (Matthew 12:33-37, underlined for emphasis)

Colossians 3:17
"And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him."

1 Peter 3:10
"For, whoever would love life and see good days must keep his tongue from evil and his lips from deceitful speech."

Ephesians 4:29
"Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen."

Philippians 4:8
"Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things."

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

What if someone says,

"Dang! I flippin love Jesus!" (but replace "dang" and "flippin" with their more vulgar synonyms)

Is that still an evil thought?

I think it would be under Ephesians 4:29, concerning unwholesome talk. Jesus said that from out of the abundance of the heart, the mouth speaks and He said that we would be held accountable for every idle word we speak. However, God is so gracious toward us that even when we fall short of His glory, He is faithful and just and will forgive us our sins and purify us from all unrighteousness if we confess our sins to Him (1 John 1:9). If we are truly in Christ, we will depart from all iniquity (2 Timothy 2:19) and if we walk in the Spirit, we will not gratify the desires of the flesh (Galatians 5:16-26). If we are truly in Christ, we will run away from sin instead of running straight into it (2 Peter 2:20-22). We are not to walk according to the flesh, but according to the Spirit (Romans 8:1-13).

You say you know its wrong, but you don't know why it's wrong. Isn't there a problem there? If you don't know why it's wrong, how could you know that it's wrong?

I personally don't get it, as long as you aren't needlessly verbally insulting someone.

Making vulgar, guttural references to human sexuality, anatomical parts and biological functions.

Hebrews 13:4, “Marriage is honorable in all, and the bed undefiled: but whoremongers and adulterers God will judge.” To use vile words for the sexual relationship is a sin against God.
