Religion says that God loves everybody no matter how bad they are.
For some that means he only sees his love for you and does not see the bad side. This makes him out to be a crazy Romeo who does not see that his Juliet is covered in smelly boils. The crazy one here is not God but the selfish person who wants it to be all about him or her. This God has to wrap himself up in platitudes and emotional attachment to you in order to take little or no notice of your using and malevolent side. He essentially accepts you sins and all. So in many circles, unconditional love is seen as love that makes no demands. In such circles, "Love the sinner, hate the sin" really means love the sinner and forget the sin. To love the harmful person hate the harm is so forced and fake anyway. It just is. So it is no surprise that the Christian understanding of unconditional love is just sanctimonious nonsense. They show the faith is a danger to persons considered to be outside the moral boundary. Fake love harms.
For others unconditional love means God does see the bad side but battles to change you so that you can come to him for he is simply incompatible with evil. So if you are evil you keep yourself from him. It is not him but you. The Bible in the letters of Paul says he loved us when we were still sinners and sent Christ to die for us to cleanse us from sin. Christians should say that love to be real has no conditions but that does not mean it does not care what should be done with you. Unconditional love will be concerned if you go down the wrong path. It will try to respectfully help you see that but does this for it values you as a person no matter what.
Shockingly the Bible view of divine unconditional love is very unpopular. It is downplayed everywhere.
So one version of God is able to accept sinners and sins and all.
The other wants to accept them but because there is a wall put up by the sinners he is unable to. He does accept you as his child and beloved but not as a sinner.
When you hear about the unconditional love of God, you can be sure the person means a God with no real standards and who is all about what you want to do.
Let us talk about that love. It is not love but sentimentalism for if your sins are bad and threaten your wellbeing this God does not give a toss.
Unconditional love is the same as undeserved love or love that does not care what should be done with you as long as it makes you feel good and has you looked after well. It is wanting the best for others without it being about you trying to value yourself as good or for getting any good feelings/rewards. It is just love.
Those who demand to be loved unconditionally are narcissists, "Love has no buts so if you want to change me or try to you do not love me." They try to impose a good opinion of them on others and condemn them if they fail to give it.
Unconditional love these days argues that you must love yourself unconditionally and that is the sun that shines rays of unconditional love to others. So it is about you and everybody else gets the leftovers. Loving others is just an offshoot of loving yourself. That is not unconditional love for others at all. To say unconditional love is about you fulfilling a need to just love or to feel loved is strange. If it is about your need to love a particular person and not because they need it from you then what? That is just a form of self-glorification and lying to the object of this love.
Love is a free gift that asks for nothing back not even love.
It wants others to be happy even if it means they have to leave you and stop loving you. It celebrates their happiness.
Conditional love then is mild hate for it is about rejecting and devaluing the person in such a way that it looks like accepting and taking while it looks like giving. It is a lie.
Hate is an evil but evil has its problems too as well as love and is one of the reasons love is not as clear in meaning as it likes to look.
We have learned that love is vague for its opposites are vague too and we all mix love and evil together. Unconditional love then is a lie. To say God loves us like that is an insult for how can creatures like us know what unconditional love means? It will be coloured by our warped and prejudicial idea of love.
