I hate my inlaws (MIL, SIL, BIL) for the following reasons please let me know how to solve my hatred.?

You can't hate somebody because of their way of life. Your MIL's appearance, their worship habits, these are such shallow things that are bothering you. Your family dynamic is different from others and to hate them because of their family dynamic shows ignorance on your part. Accept and love people for who they are. If your unhappiness with their lifestyle causes spats with you and your husband you need to change yourself and fast.
