Salaam Allahikum, Big claim to make, seems a large consensus of people agree they are, along with hundreds if not thousands of scholars. May I ask what qualification you have to make this claim. I know a guy who has studied the Quran from 8 years old till now (30). and his father is a Sheikh who studied his whole life. Starting with Quran. Saying there is no Shariah, though, is odd. Since Shariah is the law based in the Quran. There are additions to Shariah based on Hadith (which if you are adamant did not come from the Prophet (PBUH) you can simply ignore that portion and still maintain a good life), which are more constricting, but not to an oppressive way. Hadith and Sunnah aren't accepted by Shi'a either, at least not a majority of Hadith. So I must ask, how do you pray Salaat? Where did you learn that? Lastly, try not to be so combative, you might find people are more receptive to your point, and Insha'Allah you might learn a thing or 2 yourself.
