We are a selfish species like all animals. Looking out for ourselves, everything we do is based on cost-benefit and reproductive fitness.
In nature animals are only "Selfless" when it comes to their own family, because preserving whatever family they have extends the duration of their gene lineage.
Even simping is a survival strategy, as desperate and sad as it is (like a fish inseminating a female fishes eggs while she is not looking).
The only problem is humans are delusional and believe we are unique and live under the guise of a fair and just world beyond the laws of nature. We deny deep down that we are no different than the dog eat dog world out there. That's why you have redditards virtue signaling to deflect from their own flaws. That's why simps have to play mental hoops and pretend that their simping is something virtuous and noble when it's not. It's a desperate reproducing strategy wired in their brains whether they know it or not for lower tier males in human society. Then they get pissed at incels and project their frustrations on to us in order to avoid any self-reflection.
