Mushrik is non muslim. It is a Sin, but they have the option to come in fold of Islam or 2 others as mentioned in my other replies.
Qadiyani claims to be Muslim. For Muslim it is mandatory to give Shahdah that Prophet Mohammad PBUH is the last prophet sent by Allah Subhanawtallah. First Kalma.
So, Qadiyanis do recite Kalma Awal, but they say that Prophet hood is completed on Mirza Qadiyani , He is Essa, he Is Mussa he Is Ahmed etc.
For A muslim, doing such thing , have 2 options , denounce or get killed (Because, he / she was enlightened but opted to go out of Islam to Kufar, thats why A Murtid is more punished then a mushrik. You can also call it "Pehlay ghar ki safai, phir bahir ki"
Now, if you are hell bent on twisting simple stuff, then be on your path.
This is my last reply to you.
