Am I wrong to say that one of the key tenets of Christianity and Islam is Missionary responsibility? You are told to solicit the religion. You need to convert the non-believers. Am I wrong? ...
Yes, that is not correct. In Christianity there is indeed a missionary responsibility, but that is not a need to "convert the non-believers". It is not possible to convert someone to Christianity any more than you can convert lead to gold. All Christians can do is to make sure people are aware of our views. Those that choose to can accept it, while those that do not accept it are free to reject it, as you have done. You are aware of the choice, and you have made your choice. The same holds true in reverse. I am aware of your views, and I have made my choice. I respect your right to make the choice you have made, and I only wish the same in return.
With respect to Islam, their missionary orders are somewhat different. It is good news for both of us that most modern Islam sects no longer adhere to the original perspective that non-believers were to either convert, or die.
The bottom line is that I think that the more we understand about each others views, the less likely we are to have hostile confrontations over religions. I have friends that are from many different religions, and we always have respectful discussions when the subject comes up.
With regards to Tebow, I wouldn't do the things that he does, but I don't begrudge him the right to follow his own religious views the way he sees fit to do so. I do admit that I suspect that if he were a Moslem, and instead was visibly praying towards Mecca, people like Bill Maher wouldn't say a word.
