You don't talk with that conviction and depth of understanding unless you believe it or you are a sociopath.
Now, will he highlight and emphasize abortion during a general campaign....I doubt it. It is not what makes him stand out. It will drive away some of his younger libertarian voters who have never voted before or who used to vote Democrat before they realized that government is the problem.
I have no doubt that he would govern strongly pro-life.
While other social issues like gay marriage are important they don't even fall into my top 10. I don't care what those people do. I realize that the whole thing is about getting their hands on my money and having me endorse their behavior. My money is being stolen from me everyday in much larger amounts than they could come close to. I will never endorse their behavior. In the grand scheme of things there are bigger fish to fry.
In a more libertarian world with no Social Security, no federal funding of Hollywood or other arts, the diminished power of academia, free unregulated markets that don't require vast HR departments to comply with every government diktat, free market health care systems that require consumers to pay their share for what they consume, etc...the homosexual's power would be drastically reduced anyhow. So, electing Paul may accomplish the things you want without specifically even trying to.
