If you ask most Christians this question, many if not most would say something to the effect "no, of course not". One euphemism commonly repeated is "love the sinner, hate the sin", but this isn't found in the Bible, but rather was said by Mahatma Gandhi, a Hindu, yet many Christians repeat this as if it were Scripture.
First, our authority on a topic needs to come from scripture, not what the preacher or some commentary says.
II Tim 3:16
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
II Peter 1:20
Knowing this first, that no prophecy of the scripture is of any private interpretation.
Let's look at a few examples that seem to indicate that a blanket statement such as "God loves everybody", or "we're all God's children", just isn't supported in scripture.
Examples of God hating individuals
Lev 26:30
And I will destroy your high places, and cut down your images, and cast your carcases upon the carcases of your idols, and my soul shall abhor you.
Gee whiz, that sounds mean...how come we never hear that preached in churches?
Deuteronomy 22:5
The woman shall not wear that which pertaineth unto a man, neither shall a man put on a woman's garment: for all that do so are abomination unto the LORD thy God.
Psalms 5:5-6
5:5 The foolish shall not stand in thy sight: thou hatest all workers of iniquity.
5:6 Thou shalt destroy them that speak leasing: the LORD will abhor the bloody and deceitful man.
Psalms 6:8
Depart from me, all ye workers of iniquity; for the LORD hath heard the voice of my weeping.
Matt 7:23
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Psalms 10:3
For the wicked boasteth of his heart's desire, and blesseth the covetous, whom the LORD abhorreth.
The scriptures are telling us plainly that the Lord does not just hate sin, but the sinner also.
Hosea 9:15 God hated them....hmmm, not just sinful actions. Some say this is just Hosea saying this, but where is God rebuking Hosea for saying this? Again, II Tim 3:16, he spoke under the inspiration of the Holy Ghost
Proverbs 1:24-30 doesn't sound like God is loving toward those who have rejected him, this also rebukes Calvinism because they did not choose to fear the Lord.
for example, in verse 26:
I also will laugh at your calamity; I will mock when your fear cometh;
Now when calamity comes upon them and they call upon the Lord, He will not answer them. This is an example of a reprobate as mentioned in Romans 1
II Tim 3:1-8 speaks of those being reprobate concerning the faith and to turn away from them.
Acts 1:16-20 concerning Judas which the Holy Ghost spake by the mouth of David which references Psalms 69:28(let his habitation be desolate) and 109:7-16 (let his bisopprik take)
Psalms 69:28 says let them be blotted out of the book of the living, gee that's pretty harsh...
Psalms 109:7-16, Gee this passage sounds pretty harsh also toward individuals, not just the sin
Acts 13:22 God says that David, son of Jesse was a man after his own heart
Psalms 139:21,22 David, under the inspiration of the Holy Ghost says that he hates those that hate the Lord. In verses 23,24 he says "search me and see if there be any wicked way in me".
Some might say this was just David speaking on his own accord, but where is the proof of this. Is David ever rebuked by God for saying these things?
Common objections
Some will use the verses below to justify a blanket
John 3:16
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
note: For God so loved the world. This is past tense.
I Tim 2:4
Who will have all men to be saved, and to come unto the knowledge of the truth.
II Peter 3:9
The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
Yes, God would rather everyone get saved. God showed his love toward the world by sending His Son in the flesh, that the world through him might be saved. Yet some would refernce this to invite homosexuals, pedophiles and other degenerates into church to have cookies and koolaid with the children.
Yet there are those that the Bible speaks of who hate the Lord and have rejected His offer of salvation one too many times. This is the meaning of a reprobate.
Romans 1:27
And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
Those that hate the Lord
II Chronicles 19:2
And Jehu the son of Hanani the seer went out to meet him, and said to king Jehoshaphat, Shouldest thou help the ungodly, and love them that hate the LORD? therefore is wrath upon thee from before the LORD.
Summary
Helping your unsaved,stubborn neighbor who has yet to believe and trust that they are bound for hell yet Jesus died for their sins is one thing. Helping those that hate the Lord is another. Your neighbor might not yet understand the good news of the gospel, but they hopefully aren't actively involved in things that promote wickedness, blaspheme His Word, or persecute God's people. This world is full to the brim with degenerate people who despise the things of God and are hard at work trying to turn His truth into a lie.
