You commit apostasy of you refuse to continue to follow, obey, or recognize a religious faith. You tell me, ARE you an apostate?

Sadeq Mullahlah was beheaded for apostasy even though he denied the Saudi Arabian theocracy crime....his last words before a very sharp blade severed his neck completely : " I AM INNOCENT YOU ARE OPPRESSIVE " A Saudi Princess and her lover were both beheaded because she refused to marry an arranged marriage. ...

Yup, if you once attended church and believed in it.
Definition of apostate: a person who renounces a religious or political belief or principle.

Apostasy is the abandonment of a religion. So, it depends upon how you view abandonment. I think your former fellow Christian would think so, but I think it’s readonable for to assume you were never a member to begin with. It depends upon your measure I suppose. If behavior sets are your measure, then you are. If you’re personal stance and self identity is the measure, then your not.

You would be a heathen. Apostate and infidel are reserved for former believers.

Although you say you were never "truly" religious, if you were a member of, participated in, attended religious activities, I would say that your are an apostate. If you were never involved with religion, a church or religious activities in any way, I would say you are NOT an apostate. Just my opinion of course.
