Islam was never a religion of peace , it was founded by a warlord who executed people , destroyed towns , took and sold slaves as well as marrying many women and a little girl. It’s basically the same as if Atilla the Hun or Genghis Khan founded a religion
it was spread by the sword since day one , his direct followers were massacring each other immediately after his death too.
its just dishonest to compare Islam with Buddhism , Hinduism, or even Christianity
