Would you believe that I used to be a good man
Did something change? Why are you no longer a good man?
I've become a misogynistic person along the way.
While it is good that you recognized how you changed for the worse, it still is wrong to choose to continue to be a misogynist. You may have had negative experiences with women that have changed your outlook but you shouldn't let those experiences alter your personality forever. It would be a good idea to speak with a therapist in order to process what happened to you and resolve your negative feelings towards women.
A misogynist is a good person just driven mad by modern society.
I don't think it's good to make excuses for being a misogynist. It's better to just get help understanding why you have those tendencies, so that you can over the behavior.
