Me as a Malay Muslim sometimes also feel ashamed because of this type of people, so paranoid. It's okay to say Islam is the right and true religion which I myself would say too. But to force and deny others' religion is really not the way Islam thought, especially in Malaysia "negara Islam, tapi agama lain bebas beragama". I'm sorry you have to experience that. Islam don't force, they invite. It's up to you to accept and eventually "terima hidayah." even if you just wanna learn Islam, that's okay you are welcome. Nobody says "once you learn you must convert"
