While PUA methods, also known as Pick-up artist methods can certainly be considered as misogynistic depending on the cases. If you are looking to exploit a woman by using PUA methods in any manner whether emotional or sexual, then it can be considered misogynistic.
This is because PUA methods usually start with objectification where a person totally objectifies a woman based on her body and then decides whether he wants to apply his PUA skills on her. This is the mindset that encourages misogyny which is wrong according to most people. Everyone has his/her own set of moral standards, however.
