I don't know who George Grant is but will find out. However, abortion is a legal issue, not a religous issue in terms of government (state) intervention. I am pro-choice and while to many that means pro-abortion, it is absolutely not. The billboards with the babies is excellent. I even liked the ad that was for some reason scrapped for the superbowl about Obama and the single mom. I have no problem with any groups offering alternatives, as long as they are willing to take it past the simple birth.
I am also not implying that all Christians hate homosexuals, because I know that they do not. I'm referring to the 'conservative' movement in Canada that hates the CHRC because it inhibits their rights to preach that homo-sexuality is a sin. Clerics have a great deal of power over their followers, and if simple common decency doesn't tell them that it is wrong to preach intolerance, than someone has to step in.
Charitable acts are one thing, and I'm glad that you like to help out at soup kitchens, etc. My sister is on the board of our local one and it is very successful. However, while it is not the gov't's responsibility to save our souls, it is their responsibility to protect their citizens. Social programs are a must, and meaningful attempts to keep all citizens fed should always be a priority. Hunger is the basis of revolutions, so keeping the wolf away from their door, might keep them away from yours.
