Too Laid Back?

I have always been pretty easy going. I like most people. I don't care about your colour, age, sex etc. you are a good person or a bad person. I never really thought too much about Canada's future. We are a great place to live and I always thought we would be. Till recently. Now I am begining to question where we are going. I am thinking that our immigration policies are too lax. What started me thinking about it was when my yougest was up for suspension from school because he wasn't vaccinated. (He had a deathly fear of needles and had managed to keep the warning notices from us) A short time later there was an epidemic of German Measles (Rubella) in our area. It seems that certain groups are exempt from vaccinations. Our friends sister walked around town while she had the disease, while she was pregnant!, and scoffed at those who told her to stay home. Not only didn't she care about her own unborn child, but she purposefully put others at risk. Should people be allowed to immigrate to Canada when they won't be vaccinated for religious reasons? How can we stop major diseases when we harbour reservoirs of these diseases in our community? Polio, TB, whooping cough and other major diseases will always be lurking waiting to strike especially when our immunity wanes.
Should we also ask whether or not you believe in the seperation of church and state? If you don't and you do not accept this seperation and believe in tolerance for other religions then sorry we don't want you. You will not fit in to our society. We also don't want you if you are going to come here and finance violence in your former homeland. There was interesting article that said with our low birthrate our country and way of life is doomed. As we realize that we are no longer sustainable as a culture we will not stand up for our rights, because, hey we are going to die out anyway so why fight too hard for something that is going to disappear. We might as well just lay back and enjoy the remainder of our life. Would it be wrong to ask those that want to come here to renounce violence, to accept vaccinations (unless for medical reasons), to be tolerant of other religions and to believe in the seperation of church and state.
