The left has failed to do anything very useful for a while now. I would say Gay marriage was the last legitimate fight that has been won. Now it seems they have turned their attention on simply trying to dissolve every single construct and institution that has existed since the dawn of time.
It's clear these people want a completely anything goes society where every individuals action must be respected and their decision is final.
The average person doesn't take it too seriously, but within our media, schools, government, police force.... these topics are given a disproportionate amount of focus. Society is without doubt being shifted by this agenda regardless of how seriously people might take them or not.
The thing is the people who are pushing the agendas all seem fairly unhappy to me. The institutions and collectives that they want to destroy are all the things than in the past gave people meaning and kinship. Taking individualism to it's ultimate ends is a road to nowhere.
