I don't hate any religion but yeah, some facts and rituals are quite unfair. Almost all religions have different rules for men and women. I don't think any religion should differentiate between two genders.
My religion as well has some facts I don't agree with. "If someone strikes you on the cheek, offer the other cheek as well." "If one doesn't go to the Church on every Sunday, he is a sinner".
Religion shouldn't make someone lose their self respect or make anything compulsory for a person else they are called sinners. I'm not an atheist but do criticize religion at times.
Everything that your heart says is wrong, its wrong. Like you said your religion say you to
"If one doesn't go to the Church on every Sunday, he is a sinner". its wrong because your heart did not believe on it. Because NO one religion bound you to pray. There are out comes if you dont pray, but not the boundness.
In order that to believe in God and love him - not necessarily to walk in a church every Sunday. Atheists anymore believe in scientifically reasonable things. In a difference from science, there are many not truthful things in religion.
