You feel your positions aren't strong enough? I don't feel as though positions are actively changed, rather they reflect your opinions and if they just happen to be lukewarm attempting to develop them into something more than they are makes them less your own. I agree that a politics test might help you to identify your political standing better, a good test may find you questioning things you have previously not given enough thought about (that's what one did for me awhile ago.) Your opinions are somewhat towards conservative republican but are you do not feel you best identify with that party because of the strength of them? Another opinion of mine is to avoid examining what a political party views as something that your views should better align with. Again this is an opinion but I feel as though my independence from parties allows me to examine politics with a level of skepticism that aligning with a party dictates away.
Try searching "Who I side with" or "I side with" on a search engine, I think you'll find the quiz I took not too long ago, it examines your beliefs with the beliefs they infer from the presidential candidates, I then examines some of their philosophies and histories with a little more detail to see what I understood. There is another quiz somewhere that I forget the name of that creates 2d chart, liberal vs conservative on one axis, and authoritarian vs libertarian (I think) on the other axis. It also attempts to plot some notable historical figures for you to examine.
