Sin remains sin, no matter what humanity thinks about it.

Pride is sin.
Greed is sin.
The love of money is sin.
Lust is sin.
Adultery is sin.
Vindictiveness is sin.
Cruelty is sin.
Bearing false witness is sin.

If this partial list bothers you, take it up with God, he's the one that created it, my job is to simply remind people that these things are not up for debate, nor can they be changed by any act of man.  God has ordained what is right, and what is wrong, based upon his own holiness.  Our willingness to accept this standard, and change our behavior accordingly (by the power of the Holy Spirit) is a necessary beginning of discipleship.

Anyone who continues in sin is not born of God (see 1 John 3:6), anyone who does not produce evidence of the fruit of the Spirit is not a child of God (see Galatians 5:16-26).  This is not negotiable, if anyone connected with a church told you otherwise, they'll have to answer to God for that one day.  Our culture regularly glorifies the sins listed at the beginning of this post; God condemns them.  You choose.
