(1) We want to tell these radical followers of Islam that before ex-Muslims, your own Prophet will first come under the attack of your blame of cowardice, while according to you, your prophet didn't dare to claim his prophethood openly for the first three years.

(2) When your Sahaba (companions of Muhammad) hide their Beliefs to avoid HARM, why don't you blame them and your Quran for being COWARDS?

Quran 3:28: (Let) not take the believers, the disbelievers (as) allies from instead of the believers. And whoever does that, then not he (has) from Allah in anything except that you fear from them, (as) a precaution.

While ex-Muslims have to face the danger to their lives from Islam and its radical followers many times more than what your Sahaba had to face from the pagans.

If pagans put restrictions upon preaching Islam and conversion of religion, then they acted wrongfully. But unfortunately, Islam and its radical followers are themselves following the Sunnah (practice) of those pagans, whom they condemned for that crime. Actually, Islam and its followers act worse than pagans, and their ZULM is many folds more than that of pagans. Radical followers of Islam see the speck in the eyes of Ex-Muslims but they are unable to notice the log in their own eyes. These are only the Double Standards of Islam and its radical followers.

Ibrahim declared her wife Sarah to be his sister and also sent her to the King

Sahih Muslim, 2371

Prophet Ibrahim never told a lie but only thrice: ... He had come in a land inhabited by haughty and cruel men along with Sara. She was very good-looking amongst the people, so he said to her: If these people were to know that you are my wife they would snatch you away from me, so if they ask you tell them that you are my sister ... so he (the king) sent someone and she was brought to him, and (instead of fighting against the kidnapping of Sarah) Ibrahim stood in prayer ... (and the tradition further tells after this cowardice of Ibrahim, Allah had to defend Sarah himself from being raped by the King).

Are you not going to declare your Prophet Ibrahim to be a coward now?

Conclusion: Ex-Muslims have all the right to hide their identity to save themselves from the HARM of Islam and radical Muslims. And these radical Muslims should be ashamed of their evil intentions of killing innocent ex-Muslims, and they should reform themselves instead of blaming ex-Muslims for cowardice.
