If you believe people are bound to sin, and salvation is not a choice, you are merely chosen, you just follow, then ofcourse your ideas flow.
If you believe in love and Christ we are given the freedom to choose Him, and walk in righteousness, then it matters how you define this freedom and righteousness. To us therefore it also matters if you dismiss morality as legalism and call it evil.
It gets worse if you call those who take Jesus are his word lost, you make yourself enemies of the very gospel you claim to follow. So it gets confusing, especially if many in your camp deny sorting out sin, emotional reality and love in their own hearts and claim this is not the realm of the Holy Spirit or following Christ. So ofcourse we react against such ideas, it speaks against our experience and our understanding of walking with Jesus.
We have nothing against anyone personally, it is just our faith.
