Ramadhan:Why do all People who had no religion and those who have converted to Islam Say they are happy?

sura 9:29 fight those who do not profess the true faith [islam] tell they pay the poll tax with the hand of humility; sura 9:5 kill the non-believers wherever you find them. sura 2:193 sura 8:39 make war on them until idolatry is no more and allah's religion reigns supreme sura 9:123 murder the non-believers; 41:14 47:4 48:25 and hundreds more suras and hadiths calls for the death of non-believers. why not look up all the suras and hadiths like these and post them?
