Vedas group charecters of individuals into three: 1. Satviga 2. Rajasa and 3. Tamasa Most of the points you have mentioned belong to type 3, i.e Tamasa.
For your point 4, Have you seen air? If you don't see, do you deny the existence of air?
For your point 6, Hinduism allows different ways of worshipping God. "Rupa" and "Arupa". "Rupa" means giving a shape, color and charecter. For example, Ram or Krishnan. "Arupa" means without any of these. There is some thing in between. That is like "Lingam". Depending on the maturity of the individual, he can choose the way he wants to worship. For example, Ramalinga Swamigal worshipped God in the form of divine light.
Regarding your point 8: Swarg and Moksha are different concepts. If your "Karma" (deeds) are noble, you reach Swarg. Swarg is not ultimate. Reaching and dissolving your soul with Paramatma is the Ultimate.
Your point 7: There are concepts like GYANA YOGA and KARMA YOGA. What you are talking about is KARMA YOGA. When you follow Karma Yoga, you may or may not believe in God. You do your duty conscientously. That is good enough. You do not need to believe in God, but still you can continue to be a Hind. That is the greatness of Hinduism.
I have one request to you and people like you. Please DO NOT start mudslinging with half baked knowledge. Try to get deeper knowledge or keep quiet.
