Yasser Arafat, Saddam Hussein, Bashar Assad, and Abdul Gamel Nasser are all examples of secular Muslims.
The secular Muslims of the PLO and Fatah have murdered far more Jews than the religious Muslims of Hezballah and Hamas.
If someone identifies as a Muslim, they are identifying with a Nazi religion that calls for genocide against all non-Muslims.
If someone disagrees with the genocidal commands of Mohammed in the Koran and the Hadith, then they are not a Muslim. It is not like a Jew who is secular and does not accept the Torah. A secular Jew is still a Jew because the Jews are a people. Muslims are not a people, they are a religion. If you reject the teachings of the Muslim religion, you are not a Muslim.
Of course, there are Muslims who are "nice" and "polite" because it is in their interest to act that way. But if there is a war between Israel and the Muslim world, you can be sure that they side with their fellow Muslims. So they are siding with the purveyors of genocide and holocaust.
The Iranians fanatically supported Khomeini and the Muslim terrorist Nazis for decades. But now some of the younger Iranians are suffocating under the oppressive and corrupt rule of the ayatollahs and mullahs. They do not oppose the Iranian regime because of moral concern over the regime's desire to perpetrate a holocaust against Israel. On the contrary, many opponents of the regime support the nuclear-bombing program. But they want more freedom and opportunity for themselves. This does not make them moral or good people. If their personal lives were freer and more prosperous, they would be supporting the genocidal goals of the regime as they did for decades.
In conclusion, the only good Muslim is a former Muslim.
