If someone is athiest, they have 3 positions on morality. Either:
Morality is objective and based on biological need for human flourishing (reproduction) which means refusing to have kids, being gay, and abortion, should be considered immoral to them.
Morality is subjective and determined by the society, and becuase the society as a whole think that the lgbtq movement is immoral, the athiest should agree, or consider themselves immoral based on their own standards
morality is subjective to each person which basically makes morality a preference. If this is the athiests view then they have no basis to complain about what anyone aught to do. A group of people could appear and decide to kill all atheists and they would have no moral basis for saying its wrong. It would be like saying somone is wrong for thinking blue coolaid tastes better than red.
So basically atheists should not agree with the lgbtq ideology and similar left wing stances but they do because they are inconsistent.
