the wife beating verse

As Muslims we are told by the Qur'an to hold to the rope of Allah and to follow what the Qur'an and the Sunnah teaches. So with many things Muslims follow what has the most evidence for.
Some viewpoints are strong some not.

But yeah i totally understand what your saying.

Not every muslim believes in the sunnah at all and most dont believe in all the sunnah because some of the hadith are ridiculous, including stories about muhammed stoning a monkey to death for having bad sexual relations

Yes. Some Muslims don't follow the Sunnah. The majority of Scholars and Tafsir's written use the Qur'an and authentic Hadith's.
