Earlier quoted context omitted.
Your logic is tautologous. Evolution seeks no such things. Evolution just happens and is random. It's quite likely we have many traits which are not advantageous for survival, especially in our modern world. Appealing to evolutionary psychology is an intellectual and argumentative reductionist shortcut.
Exactly. The reductionism is just too easy in these arguments with every behavior contorted to project onto a sexual / survival basis. There is no quarter given for things simply being what they are.
There are many things for which the evolutionary cause is not obvious to us, but it doesn't make sense that there would just be lots of random truly superfluous aspects to us.
