Well; allow me a member of the rather radical left, to try and explain things.
As a fellow Canadian, I think I can add a few things here that may have been missed. I'll get to Conservatives, and in particular Mr. Harper, in a moment; but first let me do a quick overview on the Christians.
I think in the case of the Christians; it's very much returning what we receive from them as a community. There are radical examples, like 'preacher' Fred Phelps; and some not so bad examples of say United and Anglican churches that are more welcoming to homosexuality.
On the whole; I do believe that given time, the Churches will eventually open themselves up to the reality that we're not going away, and will at some point give up this little crusade they are on when it comes to same-sex marriage and the like. However; change in any faith is slow, so I doubt I'll see this in my life time.
The reason why; perhaps Christians in particular are singled out, is the aversion to same-sex marriage. (I'll touch more on this when I talk about the Conservatives.) But essentially, to some groups of people, to identify as Roman Catholic and be gay, is seen as a hypocrisy, as faith denies a right to part of who you are.
Then of course, there's the practice what you preach. "Judge not lest yea be judged" seems to have been abandoned, as it's condemn what you think is wrong because God probably hates it too...And don't get me started on Leviticus; keep in mind, that's the Old Testament, which is essentially Judaism, which last time I checked; wasn't Catholism.
Now, that's about all I've got to say on the Christian perspective.
As for the Conservatives; where do I begin?
There's more reasons than just Conservative stances on gay issues; although, for many that's a selling point. Just look at the track record Mr. Harper and his government has in office:
Ran for: More accountability and transparency in government
Canadians Got: An accountability act that doesn't work; a Montreal man appointed to the Senate and given TWO, as of today, plum Cabinet positions despite being unelected; the M. Bernier Affair; and a gagging of Conservative MPs so much to the point that none are allowed to speak without permission from the PMO.
There there's of course the slashing to the social programs: the women's offices that the PMO closed; the destruction of a low income legal defense fund, etc, etc, etc...
Conservatives in general; even without using their anti-gay stance; are bad in so many ways. And anyone familiar with political science, will know true conservatives don't exist anymore. In fact, the idea of a minimalist state is actually a Liberal, classical, idea. Conservatives are just neo-Liberals, in terms of economic and social policy.
Personally, I'm a fan of moving ahead into the future; not moving back into the past, which is why this ideology just doesn't work.
So, that's my attempt at an explaination as to WHY there's so much 'ill-will' towards Christians and Conservatives; simply because of the hypocrisy of both groups.
And on a side note; I'll front you that just because you belong to a group doesn't mean you agree with ALL of their policies. Just because I'm a borderline Marxist; doesn't mean I agree with all of Marx's conclusions, but I do think he got some facts right.
But yes, I do hope at least one person actually reads all this.
