I'm not opposed to asking questions that are appropriate. I'm sure you are making reference to the Conservatives who can be kindly described as being thin on platform.
As I have said, I don't really care if my MP is very religious privately, or secretly holds beliefs in the existence of UFO's (Jimmy Carter did, and he was a reasonably good president imo), just so long as those things don't become part of their reason for wanting to be elected.
As much as I would like to know if my MP or the candidates running in my riding harbour something like racist or hateful views, if they shut up about those views, then how am I to actually know? If asked, they could lie; but I wouldn't know that either. It's certainly not something that I would like of my MP, but it might possibly exist out there. I'm assured that if these individuals do ever open their mouths on such a topic, and end up making what are clearly idiotic statements, they ought to become a target for immediate and pointed questions for clarification.
If an MP I really liked said that he/she was personally opposed to abortion, but recognized that it already existed in society, I would have a tough time voting against that person if I found their other political views in agreement with my own. Of course, I would be taking a risk if the issue of abortion ever did come up. The same is so with same-sex marriage. I'd imagine many Canadians were and still are opposed to the idea. It would seem that a significant portion of them, even though opposing such marriage, had a live-and-let-live attitude regardless.
But as for platform or policy statements of a party, they are open territory. Ask away.
