PROPORTIONAL REPRESENTATION= BC NDP DEMISE

"IF" the BC NDP allowed the BC Green party to establish a proportional representation system in British Columbia, this would guarantee the BC NDP never forming a majority government again, & would result in the demise of the BC NDP as significant political force in the province... 
 
Proportional representation would lead to:

- a substantial increase of BC Green party MLAs- none aligned with other parties; 

- a proliferation of boutique-issue parties, 

&  as a consequence: 

- the fragmentation of "right" & "left" leaning political philosophies in BC’s political apparatus...

Would the BC NDP risk, in effect, permanently barring themselves from being able to, in future, form majority-governments BC??

IE: by forcing proportional representation upon BC- would the BC NDP be OK with the unavoidable consequence: 

... nullifying all possibilities of the party in future forming a majority BC govt & passing legislation that it alone supported??
