Is gender abolished in the New Covenant?

Are laws regarding male and female now abolished in Christ? Shouldn't Christians, according to their own doctrines, now be ignoring Moses' laws against transgender and homosexuality the way they ignore circumcision law? Because in Christ there is "neither male nor female?"

Critical Question asked. If when Paul said, "there is neither Jew nor Gentile" he meant that the laws which differentiate between Jew and Gentile are nullified, why then do Christians still differentiate between male and female? Why haven't Christians ignored the laws regarding male and female differences, being the same text that says "there is neither Jew nor Gentile" also says "there is neither male nor female?"
What was nailed to the cross?

Did God came to earth as a man only to blot out his own handwriting?

Isn't it preposterous to assume that somehow God, after writing the law into tablets of stone with his own FINGER, and then after judging Israel according to this handwriting for centuries, then had to come to earth and become a man so that he could undo this handwriting completely?

Exposing the truth regarding the ordinances that were "blotted out" by the cross of Christ.

We also examine tithing, circumcision, sabbath keeping, Hebrew Roots movement, and we cover how the mystery of Christ in you was that the Gentiles were a part of the kingdom without the written laws of Moses which never applied to Gentiles.
