only things that I know of “sharia” from Qur’an are:

• one hundred lashes for adultery,
• eighty lashes for accusing chaste women of adultery and failing to produce four witnesses,
• Qisas,
• cutting the hand of the thieves (when very specific conditions are met),
• total prohibition of interest in debt,
• hiraba

I wish you criticize them only if the laws of your country solved these problems efficiently (unless you don’t consider them problems),
And it is kinda strange that you’re hurt when you didn’t have contact with Islam?
