The Koran says you can not force someone to convert to Islam, yet if a Muslim converts to another religion,?

he or she is killed, usually by a family member. MUSLIMS----how do you explain this? And how do you explain honor killings---killing a female family member for an inproper ual affair, or even if she is d. If you all keep claiming your religion is not evil like we think, how do you explain all this. And please--- no "Allah knows best" or death threats towards me. That only reinforces the view that I am trying to change.
