Secular ethics all derive from the Right to Coom. Once you have accepted there is no such thing as "higher purpose" or "ultimate meaning," let alone an afterlife or eternal union with the Divine or reincarnation or whatever, only the eventual annihilation of everything, then the most important thing in your life is to experience as much pleasure as possible. If it pleases you to have kids with your wife, go ahead. If it pleases you to ejaculate in a cross-dressing man's anus and then buy a baby from a woman so you can LARP your fetish in front of others, then go ahead. The important thing is that no law or social convention gets in your way.
From the Right to Coom flows all other morality and law in secular liberalism. We have a variety of laws and conventions to ensure women can chase orgasmic highs without inhibitions or economic consequences. We have free AIDS drugs so fags can coom all they want and not die from it. We have speech codes to ensure nobody makes fags or troons feel bad about their paraphilias. "Free speech" has been circumscribed to refer mainly to porn (because coom) while apparently not covering your right to not bake a fag celebration cake (because coom). We spend enormous sums to rush narcan to junkies because they have a right to get high as many times as possible (which is just a form of coomerism).
The Right to Coom also leads to open borders. Since young men and women have zero duty or moral pressure to sustain society with progeny, we open our borders to barbarian hordes to try and sustain our wealth (just another form of coomerism) and our welfare systems (which exist to mitigate the consequences of coom). The only real alternative is to knock the Right to Coom off its pedestal, but that's impossible in a secular, liberal order.
The main alternative to the Right to Coom is secular authoritarianism, like Communism or fascism, where there are no rights (because who really cares if some irrelevant worm coomed enough in his short life?).
