You ask a tough and slighltly controversial question. Personally, I agree with you that both men and women are alike when it comes to keeping the hair and I think women doing their eyebrows is equivalent to men trimming their beards. There is a delicate balance that needs to be gracefully maintained between your self-esteem and value-system - one that is a DISTINGUISHING FEATURE a true Sikh of the Guru. Through the powers of prayer and projection, one can attain this state where preservation of the value-system provides the self-esteem and attracts like-minded people. So there is no need to worry. The Guru will provide, prevail and help you prosper.
