Not a strawman, not ad hominem. Untwist them, they're in a bunch.
1. What's your basis for saying that he primary motivation is to control women's rights? If so, please provide evidence for it. This seems like a straw man to me.
2. Assume that's so. Does that simple fact automatically mean his reasoning isn't valid? (Answer: No. Motives don't invalidate reason, but they can lead to invalid reasoning. Still, what makes reasoning invalid are flaws with the reasoning itself). This seems to be an ad hominem attack because you are assaulting his character (not that there aren't plenty of ways to do that, but doing that doesn't do a dang thing to show why he's wrong, which is unfortunate).
Of course, maybe you didn't mean to imply that #1 means that his reasoning is invalid, which means that #2 isn't the case.
