How do you tackle a person with double standards?

With compassion.

You know, double standards are because they don’t know the wealth that they are carrying in themselves. 

Each one of us is a treasure house of wealth. Deep inside, you have the divinity, the light, the peace, the joy, the love that you are seeking. And when you are not in touch with that, you are trying to grab this little bit here, grab something from there. For what? Because you don’t realize that there is a great power deep within us.

So, with such people you simply have to have compassion. By having double standards they are harming themselves.
