text: a challenge to muslims? how come none of these so called muslims cant challenge the brave ex muslims? ex muslims offer 100% proof and it is from the quran. the only comments muslims can direct towards these ex muslims are to call them liars, western stoogers, or threaten them with abuse and death. i recently watched an interview that muslim critic wafa sultan had on al jazeera with 2 muslim clerics. all what these 2 men did was abuse wafa sultan. they could not answer or stand up to her critical questions regarding islam and the prophet. why so? i agree with you that ex-muslims who admit publicly that they are no longer believers are very brave.  how brave it is, to risk your life by admitting you are an ex-muslim.  for every one that admits it, how many are justifiably afraid to admit it?
