We will have to define in what way God hates sinners. I have to admit it's pretty complicated if you also read other scriptures like this one:
Rom 5:8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
My explanation is this. God has a particular kind of love for different sinners, he saves some and condemns others.As this scripture says:
Rom 9:13 As it is written, Jacob have I loved, but Esau have I hated.
Rom 9:14 What shall we say then? Is there unrighteousness with God? God forbid.
Rom 9:15 For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.
There is a general love God has for mankind for:
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.
But he has a special love for those who are His chosen. Trust me.I think if God truly hated sinners and specially those who have not believed they would not live for very long since once they are able to comprehend what is sin they would be instantly destroyed, just like anything a human being who completely hates something or someone would do. So the fact that sinners are still alive is a clear sign God loves them in some way, but He does hate them in another way according to the scripture you and I quoted.
