the erasure of gender as a normative construct is meant to further erode the institution of the nuclear family, the end goal being to engender the further alienization of most americans who will, as single parents (increasingly more often than not), trust the state to raise their children for them.  leftists don't benefit from strong nuclear families as those tend to embody conservative values - they benefit from the state having a more tangible influence in people's lives. the trans phenomenon is just one of many cynical social engineering examples the party employs for its own ends. abandoning that strategy now actually doesn't make sense in the long term.
